Value Collection JY9037284 M24x1.25 Straight Flute Tap Hss

Product Description

The VALUE COLLECTION JY9037284 is a straight flute tap designed for cutting M24x1.25 metric special internal threads in a shop or field machining environment. Built from high-speed steel (HSS) with a bright, uncoated finish, this tap features four flutes and a plug chamfer for controlled thread starting. The 6H class of fit and D5 thread limit make it suitable for standard tolerance internal thread applications. With an overall length of 4.906 inches and a thread length of 2.219 inches, it fits standard tap holders used in manual or machine tapping setups. Machinists and tool-and-die technicians are the primary users.

This tap is used in metalworking and machining applications requiring M24x1.25 metric special threads, a fine-pitch designation not found in standard coarse or fine metric series. Typical use cases include threading bores in automotive, hydraulic, and industrial equipment components where this non-standard pitch is specified. The plug chamfer style, with its moderate lead-in, is suited for through-hole and deeper blind-hole tapping where a starting taper is not required. Coolant-through is not supported, so conventional flooding or cutting oil application applies.

Key Features

• M24x1.25 metric special thread form for non-standard fine-pitch applications
• High-speed steel construction provides wear resistance across a range of workpiece materials
• Plug chamfer with 4 flutes for balanced cutting action in through and blind holes
• 6H class of fit and D5 thread limit for consistent, standard-tolerance internal threads
• Bright, uncoated finish — no coating thickness to account for in close-tolerance work
• Right-hand thread direction, compatible with standard tapping equipment and holders

Compatibility

Designed for use in standard tap holders and tapping heads configured for M24 shank tooling. Suitable for threading ferrous and non-ferrous metals where M24x1.25 metric special internal threads are required.

Installation Notes

Tapping should be performed by a qualified machinist following established speeds and feeds for HSS taps in the target workpiece material. Secure the workpiece and ensure the tap is properly aligned to the bore centerline before engagement to avoid tap breakage. Apply cutting oil or appropriate tapping fluid throughout the operation. When tapping blind holes, clear chips frequently to prevent packing and tap failure.
