Product information

Description

The KWB 238640 twist drill bit is a precision-ground, right-hand cutting drill manufactured to DIN 338 Type N standards. The bit has a 135° tip angle, cross-ground to DIN 1412 C for self-centering performance, and a cylindrical shank. A titanium nitride (gold-coloured) surface treatment reduces friction and increases tool life when drilling a wide range of materials.

Advantages

This drill bit offers high industrial quality with precision ground flutes and a hardened, titanium-nitrided coating that improves wear resistance and reduces friction. The 135° tip and cross-ground geometry provide accurate centring and stable drilling, while the cylindrical shank ensures compatibility with common chucks and drill holders. The surface treatment extends service life even under heavy load and when working with alloyed and unalloyed steels, cast steel, sintered steel, nonferrous metals and hard plastics.

Suitable for

Alloyed and unalloyed steel
Cast steel and die castings
Sintered steel components
Nonferrous metals: copper, bronze, nickel silver
Hard plastics

How to use

Secure the KWB 238640 drill bit in a suitable chuck or drill holder with a cylindrical bore. Select appropriate spindle speed and feed rate for the workpiece material; use slower speeds for harder metals and higher speeds for nonferrous metals and plastics. Apply steady pressure and allow the drill bit to cut without excessive force. For prolonged life and improved hole quality, use cutting fluid when drilling steels and other hard materials.

Usage recommendations

For best results, pre-drill with a smaller pilot for deep holes, maintain correct speeds and feeds for the material, and replace the bit if signs of wear or chipping appear. Use appropriate personal protective equipment and clamp workpieces securely before drilling.
