For through hole applications
- Left hand spiral flutes to push chips ahead in through holes
- Offer performance advantages over conventional high speed steel taps
- Long tap life at up to 50% higher tapping speed than HSS taps
- Plug chamfer (3-5P) - the most common chamfer for use by hand or machine in through or blind holes
- This chamfer is more efficient than a bottoming or modified bottoming chamfer
- WS39MG grade - surface treated HSS-E-PM powder metal HSS-E substrate with oxide/nitride surface treatment that provides wear resistance in nickel alloys
