Y24 Handheld vs YT24 Air-Leg Rock Drill: What Is the Difference?

Quick answer: Y24 is the handheld route. YT24 is the air-leg-supported route. Their similar names do not make the drill bodies, support systems, parts or supply packages interchangeable. If you are requesting a quotation, start by confirming how the drill will be supported, then identify the exact model, interfaces and accessories.

The difference in 30 seconds

Identify the Machine Before Choosing the Buying Route

The model label is a starting clue, not the complete acceptance record. Search results and supplier listings use Y24, YT24, YT24C and TY24 inconsistently. For procurement, replacement parts or fleet standardization, approve the route only after the physical unit and controlled supplier data point to the same identity.

Use a four-layer evidence ladder

Evidence layer	What to record	What it can prove	What it cannot prove alone
1. Nameplate and documents	Manufacturer, complete model and suffix, serial number, manual or purchase record	The declared identity and document set for that unit	A damaged, replaced or unreadable plate does not prove the machine by itself
2. Support architecture	Handheld operating arrangement, dedicated air-leg connection, actual air-leg model and mounting details	Whether the supplied configuration follows the handheld route or an air-leg-supported route	An improvised support or loose accessory does not convert one drill body into another model
3. Body and port layout	Overall dimensions, mass, handle or connection area, air inlet, water connection, cast marks and clear photos from both sides	Whether the unit matches the controlled drawing or product record being quoted	Visual resemblance or paint colour is not sufficient evidence
4. Interfaces and service parts	Shank/chuck class, flushing arrangement, hose and oiler requirements, parts manual and repair-kit reference	Whether the proposed drill steel and support package belong to the identified configuration	A shared H22×108 class does not make drill bodies, air legs or repair parts interchangeable

Use the strongest available evidence first. If the nameplate is incomplete, combine body photographs, measurements, cast marks and interface details with a controlled drawing or supplier confirmation. Do not force-fit an air leg, hose, shank or service part merely to see whether it appears to work.

Y24/YT24 identification and quotation gate

Evidence state	Buyer decision	Next action
Complete identity and physical configuration match the current Y24 handheld product record	Y24 ROUTE	Quote the handheld drill and confirm the drilling task, air supply, shank and requested accessories
The machine is clearly air-leg supported and the full YT24-family suffix/configuration is documented	YT24-SERIES ROUTE	Quote the identified drill body, matched air leg and complete supply scope
The unit appears air-leg related, but YT24C, TY24 or another configuration cannot be resolved	HOLD FOR IDENTITY	Request nameplate, both-side photographs, connection details, dimensions and any parts record before pricing a replacement
The proposed replacement relies only on a similar name, common shank class, colour or one photograph	DO NOT SUBSTITUTE	Return to the evidence ladder and identify the unit before approving drill body, air leg or service parts

Copy-ready identification record

• Buyer/site and unit reference:
• Manufacturer shown on the unit:
• Complete model and suffix:
• Serial number or asset number:
• Support method: handheld / air-leg supported / unresolved:
• Air-leg make, model and connection details:
• Shank/chuck class and measured evidence:
• Air inlet, water/flushing and oiler arrangement:
• Body dimensions, mass and cast marks:
• Photographs received: nameplate / left side / right side / support connection / ports / shank end:
• Drawing, manual or parts-record reference:
• Required supply scope: drill body / air leg / oiler / hose set / drill steel / bits / service parts:
• Decision: Y24 ROUTE / YT24-SERIES ROUTE / HOLD FOR IDENTITY / DO NOT SUBSTITUTE:
• Reviewer and approval date:

Keep identity control separate from application-class selection

This page owns the near-name identification problem: whether a buyer should enter the Y24 handheld route or a documented YT24-series air-leg route. The broader handheld-versus-air-leg selection guide owns application-class decisions such as drilling direction, feed support and operating method. Use both only when the machine identity and the job class are still unresolved.

Choose Y24 when the job needs a handheld drill

Choose the Y24 path when the operator needs to carry, support and reposition the drill without a dedicated air-leg feed arrangement. For the current PerfoMax Y24 reference, the published values include 24 kg weight, 604 mm length, H22×108 mm shank, 34–42 mm hole range, 70×70 mm cylinder diameter and piston stroke, 0.4–0.63 MPa working pressure, air consumption up to 55 L/s and a 19 mm air pipe.

Those values help screen the application, but they do not replace a site check. Before ordering, confirm the drilling orientation, typical hole diameter and depth, rock condition, compressor delivery at the tool and how often the operator must move the drill.

See handheld rock drills or go directly to the Y24 handheld pneumatic rock drill.

Choose the YT24 route when the drill needs air-leg support

Choose the YT24 route when the drilling method depends on an air leg or supported feed arrangement. Do not order from the base name alone. The current PerfoMax page is a YT24-series inquiry entry: the quotation path requires confirmation of YT24C, TY24 or an identification-required case.

This distinction matters because weight, dimensions, air consumption, hose requirements, air-leg matching and parts can depend on the exact configuration. PerfoMax therefore does not publish one combined set of final values for every item sold under the YT24 family name.

See air-leg rock drills or open the YT24-series air-leg inquiry page.

What is not interchangeable

Do not assume that the drill body, support arrangement, air leg, hose set, oiler, water connection, service parts or repair kit can move from one name to the other. Even a shared H22×108 shank class only describes the shank connection class; it is not evidence that the machines or their parts are equivalent.

If you need a broader explanation of handheld versus air-leg working methods, use the existing handheld vs air-leg selection guide. This page stays deliberately narrow so that Y24 and YT24 buyers reach the correct product path quickly.

Send these five items for a usable quotation

1. Support method: handheld or air-leg supported.
2. Exact identity: full nameplate, model suffix and manufacturer if visible.
3. Drilling task: rock type, orientation, hole diameter and typical depth.
4. Air system: compressor model, delivered pressure, hose inside diameter and length.
5. Supply scope: drill only, or drill plus air leg, oiler, hoses, shanks, bits and service parts.

For an existing machine with a missing or unreadable nameplate, send clear photos of both sides, the handle or air-leg connection area, air and water interfaces, shank end and all cast marks. We will mark the case as identification required instead of guessing from colour or one side-view photo.
