YT24C and TY24 pneumatic rock drills should not be treated as interchangeable simply because both are advertised under the “YT24” family name. Before selecting a complete drill, air leg or spare part, confirm the exact nameplate model and supplier, then compare a controlled data sheet or drawing, overall dimensions, cylinder and stroke, air and water connections, air-leg mounting interface, shank application and parts list. If those records are missing, quote the unit as an unidentified YT24-family configuration—not as a confirmed YT24C or TY24.
This distinction matters because current public listings do not use the family names consistently. Different manufacturers and resellers publish different dimensions, performance figures and accessory pairings for products called YT24, YT24C, TY24 or TY24C. A familiar blue housing, a similar handle or a stated H22 × 108-class application is useful for screening, but none proves that internal parts or mounting interfaces will interchange.
YT24C vs TY24: the direct buyer answer
| Question | Safe answer | Evidence required |
|---|---|---|
| Are YT24C and TY24 the same drill? | No universal interchangeability should be assumed. | Nameplate, supplier-controlled drawing, data-sheet revision and parts book. |
| Can they use the same H22 drill steel? | They may be sold for the same H22 × 108-class application, but the actual shank and chuck interface must be confirmed. | Shank dimensions, collar position, chuck-bushing data and approved drill-steel specification. |
| Can they use the same air leg? | Only if the exact air-leg suffix and mounting/control interfaces are approved for the drill configuration. | Air-leg model, mounting dimensions, hose/control layout and supplier compatibility statement. |
| Can internal parts be mixed? | Not from the model-family name alone. | Matching part numbers, dimensions, material/heat-treatment requirements and revision-controlled exploded view. |
| Which model performs better? | Compare only at the same test pressure, hose and lubrication conditions; then validate on the intended site. | Comparable test basis plus a defined field trial. |
The practical rule is simple: family name identifies the search area; configuration evidence identifies the product.
Why YT24-family names become confused
Several naming problems occur at the same time. Some listings place the letter “C” after YT24, some use TY24C, and others use YT24 as an umbrella name. Translation, legacy drawings, aftermarket copies and seller-specific naming can all compress distinct configurations into one commercial label. Even when two pages agree on weight class, working-pressure range or nominal hole range, they may disagree on overall length, cylinder geometry, piston stroke, air demand, hose size or air-leg pairing.
That disagreement is not a reason to average the numbers. It is a warning that the test article and the model label may not be controlled in the same way. A buyer should never create a hybrid specification by taking air consumption from one supplier, cylinder dimensions from another and a spare-parts diagram from a third.
What similarities do—and do not—prove
| Observed similarity | What it can indicate | What it does not prove |
|---|---|---|
| YT24-family marking | The unit belongs in the same broad comparison set. | Exact suffix, build revision or parts interchangeability. |
| Similar external housing and handles | The drills may follow a related layout. | Same cylinder bore, valve chest, piston, rifle bar or fasteners. |
| H22 × 108-class drill-steel use | The intended drilling system may share a common nominal shank class. | Correct chuck bushing, collar position, tolerance or bit connection. |
| Similar stated hole range | The tools may target a comparable application envelope. | Same impact energy, air demand, feed requirement or site productivity. |
| Similar blue paint or casting shape | Nothing reliable by itself. | Manufacturer, material, quality level or compatibility. |
Visual resemblance is especially weak for spare-parts decisions. A piston or valve component can look correct and still differ at a sealing diameter, port position, striking length or heat-treatment requirement.
A nine-point YT24C and TY24 identification workflow
1. Record the nameplate exactly
Photograph the complete nameplate square-on and record every character, including suffixes, serial or batch number and manufacturer. Do not normalize TY24 to YT24 or remove a “C” because another catalogue does so.
2. Identify the current supplier and document revision
Request the drawing number, data-sheet date or revision and the parts-book revision. The same commercial model can change over time, so a current document is more useful than an undated web table.
3. Measure the complete drill envelope
Measure overall length and the principal body, handle and mounting positions from defined datums. Record the measurement method. An overall length measured with a different handle or fitting installed is not directly comparable.
4. Confirm cylinder and piston geometry
Use the supplier drawing or service procedure to verify cylinder bore, piston stroke and relevant piston dimensions. Do not dismantle a pressurized or contaminated drill merely to create measurements. When a parts order is involved, the piston and cylinder part numbers should trace to the same model revision.
5. Map every air and water interface
Record inlet type and size, hose requirement, water connection, control arrangement and oiler specification. A similar pressure rating does not mean the installed hose can deliver the required flow at the drill inlet. Compressor data, hose length, coupling losses, altitude and simultaneous tool demand still control the available air.
6. Verify the air-leg interface and suffix
Identify the complete air-leg model, not just “FT160” or another family name. Compare the mounting interface, control hoses, feed travel and approved drill pairing from the relevant supplier documents. A leg that can be physically attached is not automatically a safe or effective match.
7. Verify drill-steel and chuck details
Confirm the actual hex shank, shank length, collar position, chuck-bushing interface and approved rod/bit system. PerfoMax’s YT24-family page treats H22 × 108 as an application class while still requiring the exact configuration to be recorded. Use the YT24-series model-identification page as the commercial starting point, not as permission to substitute from the family name.
8. Cross-check the parts book
Compare high-risk parts such as the piston, cylinder, valve chest, valve, rifle bar, ratchet, pawls, chuck bushing, rotation components, seals, through bolts, throttle parts and connection fittings. A supplier statement of interchangeability should identify exactly which part numbers and revisions it covers.
9. Freeze the quotation configuration
The quotation should state the exact model, supplier, document revision, included air leg and oiler, hose and water connections, drill-steel interface, spare-parts scope and inspection evidence. Attach the controlled data sheet or drawing that will govern production and acceptance.
How to compare performance without mixing test conditions
Published impact frequency, impact energy and air-consumption values are meaningful only when their test conditions are comparable. At minimum, confirm:
- pressure measured at the drill inlet rather than only at the compressor;
- air-flow measurement basis and units;
- hose inside diameter, length and coupling restriction;
- oiler, oil grade and delivery setting;
- water-flushing state and water pressure where applicable;
- drill steel, bit diameter, rock condition and feed arrangement;
- whether the published value is a limit, nominal rating or measured result.
If the basis differs, do not rank the drills from the numbers. First use the documented requirements to eliminate incompatible options, then run a controlled site comparison using the same compressor, hose, drill steel, bit, rock zone and operator procedure. Record penetration, air pressure at the tool, oil use, stoppages and wear observations. Productivity claims should remain site-test results, not universal catalogue promises.
Spare-parts compatibility: use a controlled matrix
The costliest YT24-family mistake is often not selecting the wrong complete drill; it is ordering a batch of familiar-looking spares that cannot be used. Build a part matrix before purchasing:
| Part group | Minimum match evidence | Reject or escalate when |
|---|---|---|
| Piston and cylinder | Part numbers, key diameters, lengths, port relationship and specified material/heat treatment | Only external appearance or weight is available |
| Valve chest and valve | Exploded-view position, part number, dimensions and airflow orientation | Ports or seating faces differ |
| Rifle bar, ratchet and pawls | Tooth/helix form, lengths, mating-part numbers and rotation-system revision | One component is proposed without its mating set |
| Chuck bushing and drill-steel interface | Hex size, shank length, collar position, fits and drawing | “H22” is the only compatibility evidence |
| Seals, springs and fasteners | Dimensions, material specification, hardness where relevant and parts-book quantity | A generic kit has no model/revision cross-reference |
| Air, water and control fittings | Thread/interface, hose size, port position and approved schematic | An adapter would alter flow, control or guarding without engineering approval |
Use separate bins and labels for each verified model. If an interchangeability test is authorized, document the old and new part numbers, measured characteristics, installation result and approving engineer or supplier. Never mix unverified parts back into common stock.
Common YT24-family ordering mistakes
- Dropping the suffix. “YT24” on an RFQ can erase the configuration distinction the buyer needs to preserve.
- Using photos as the specification. Paint, handle shape and casting appearance are not controlled interfaces.
- Assuming H22 × 108 proves the whole drill. It screens the drill-steel application but says little about air-leg or internal-part compatibility.
- Comparing air figures from different test pressures. The result is not a fair performance comparison.
- Buying an “FT160” leg without the suffix. Family names do not replace the mounting and control-interface check.
- Ordering generic repair kits. Seals and small parts can be model- and revision-specific.
- Combining data from multiple suppliers. The resulting hybrid specification may describe no real drill.

Frequently asked questions
Is YT24C the same as TY24C?
Do not assume so. Public sellers use YT24C, TY24C, TY24 and YT24 inconsistently. Ask the supplier to state the exact controlled model, manufacturer, drawing and parts-book revision, then compare the physical interfaces.
Can YT24C and TY24 use the same spare parts?
Only parts covered by a documented cross-reference should be treated as interchangeable. Compare part numbers, dimensions, mating components and revision. A visual match or a shared family label is insufficient for pistons, valves, rotation parts, chuck bushings, seals or fittings.
Does H22 × 108 mean the drills are compatible?
No. It identifies an important drill-steel application class, but it does not confirm the air-leg interface, internal geometry, air/water connections or spare-parts system. Verify the shank tolerance and collar/chuck relationship as well.
How should I compare YT24-family air consumption?
Use figures measured at the same drill-inlet pressure and with a defined hose, coupling, oiler and operating state. If those conditions are missing or different, treat the values as non-comparable and confirm compressor suitability from a controlled supplier data sheet and site test.
What should I send when the nameplate is unreadable?
Send full-body photographs from multiple sides, close-ups of all cast and stamped marks, overall and interface measurements, hose and water connections, air-leg details, chuck/shank measurements and photographs of known parts. Keep the unit classified as unidentified until the evidence matches a controlled document.
