Accupro T2690323 Spiral Point Tap 10-24 3 Flutes Plug Hss

Product Description

The ACCUPRO T2690323 is a spiral point tap designed for cutting 10-24 unified coarse threads in through-hole applications. Built from 3% vanadium high speed steel (HSS) with a bright finish, this tap delivers consistent thread form and extended tool life in a range of ferrous and non-ferrous materials, including titanium. The plug chamfer eases entry into the workpiece and distributes cutting forces across the leading threads. With an H3 thread limit and a 2B/3B class of fit, it produces threads suited for standard fastener assemblies in precision manufacturing, maintenance, and repair work. Three flutes provide chip clearance while the spiral point pushes chips forward ahead of the cut.

This tap is suited for through-hole threading operations in machine shop, production, and field maintenance environments. It is appropriate for use in manual tapping handles, CNC machining centers, drill presses, and tapping heads. The 10-24 thread size is widely used in electrical enclosures, HVAC equipment panels, control boxes, and light structural assemblies. Licensed machinists, tool-and-die technicians, HVAC installers, and maintenance mechanics commonly specify this size for equipment assembly and field repair tasks.

Key Features

• Spiral point design pushes chips forward, keeping the flutes clear in through-hole cuts
• 3% vanadium high speed steel construction for improved wear resistance over standard HSS
• H3 thread limit with 2B/3B class of fit for standard threaded fastener assemblies
• Plug chamfer provides gradual lead-in and distributes cutting load across multiple teeth
• Bright finish with no coating — suitable for use with cutting oil or tapping fluid
• Right-hand thread direction; not coolant-through

Compatibility

Designed for through-hole threading of 10-24 unified coarse thread forms. Rated for material applications including titanium. Fits standard 10-24 tap holders and tapping chucks accepting a 4.93 mm shank diameter.

Installation Notes

Threading operations should be performed by a qualified machinist or technician familiar with tap selection and cutting speeds for the workpiece material. Secure the workpiece and power down or lock out any machine before changing tooling per OSHA lockout/tagout procedures. Use an appropriate cutting fluid or tapping oil to reduce heat and extend tap life, especially in harder materials such as titanium. Avoid forcing the tap — back off periodically to break and clear chips and prevent tap breakage.
