Widely used for general hand and machine tapping operations
4 Thread Chamfer- For thru holes and in blind holes that allow for ample chip clearance. Easier starting and requires less tapping torque than bottoming taps.
2 Thread Chamfer- For blind holes drilled to a minimum depth that requires threads close to the bottom of the hole.
SPIRAL POINTED & SPIRAL FLUTE
Used for efficient chip disposal in production tapping operation.
SPIRAL POINTED PLUG
4 Thread Chamfer- Incorporates an angular grind at the point end of the tap which shears chips and drives them forward of the tap. Used widely in long thru holes and blind holes with ample chip clearance. They are free cutting and provide increased tap strength. Not recommended for abrasive material.
HIGH SPIRAL FLUTE-BOTTOMING
2 Thread Chamfer- Spiral flute for efficiently pulling stringy chips out of deep or blind holes in soft material.
