Through-hole machine tap, bright, solid carbide

Solid carbide through-hole machine tap, bright

Drilling tools

• Solid carbide
• Innovative tool geometry for hard machining
• Radial internal cooling
• Spiral point form D (3.5-5 turns)
• Straight fluted
• Extra sturdy design
• Shank tolerance h6
• For hardened materials up to 63 HRC, for blind-holes with long run-out as well as through-holes, do not use in RIGID-TAPPING, use tapping chuck with minimum length compensation or standard length compensation chuck.
• For very hard steels, we recommend drilling the core-hole Ø 0.05-0.3 mm larger than the DIN specifications (see table).
