Kierrep pora KWB 248068 oikeakätinen

The KWB 248068 twist drill bit is a single-piece HSS-Co drilling tool made to DIN 338 for precise hole-making in demanding materials. With a 5% cobalt alloy and a 135° split point (DIN 1412 C), the bit offers self-centring performance and reduced walking on start-up. It features a right-hand cutting geometry and a parallel shank for universal compatibility with standard drilling machines.

Advantages

The 5% cobalt high-speed steel composition increases heat resistance and wear life compared with standard HSS bits. The 135° point angle with split point provides accurate centring and easier penetration in tough materials. A parallel shank ensures secure clamping in chucks and easy interchangeability between machines. The single-piece construction gives consistent cutting performance and dimensional stability under load.

How to use

Mark and centre the drilling position, clamp the KWB 248068 drill bit securely in the drill chuck, and set an appropriate spindle speed for the material. Use cutting fluid when drilling steels and stainless steels to reduce heat and increase tool life. Apply steady feed pressure and allow the drill to cut without forcing; withdraw occasionally to clear chips in deep holes. After use, clean and store the bit to prevent corrosion.

Recommendations

For best results on stainless steel and alloyed steels, use moderate speed, continuous cutting fluid, and incremental pecking for deep holes. Replace the bit when wear affects centring or cutting performance.
