Vrták KWB 248035 1 ks pravotočivý

The KWB 248035 twist drill bit is a single-piece HSS-Co cutting tool designed for precise drilling in a range of metals and plastics. Made to DIN 338 standards with a 5% cobalt alloy, it supports demanding machining tasks. Its 135° split point (DIN 1412 C) provides self-centring drilling and reduces slipping, while the right-hand cutting geometry and parallel shank ensure compatibility with standard drilling machines and chucks.

Advantages

The HSS-Co composition (5% cobalt) increases heat resistance and wear performance compared with standard high-speed steel. The 135° point with split point design enables accurate, self-centring starts and minimises walking on the workpiece. Manufactured to DIN 338, the drill bit delivers consistent dimensions and performance and the parallel shank offers universal mounting in standard chucks and drill holders.

Key specifications

How to use

Secure the twist drill bit in the drill chuck, ensuring the parallel shank is clamped firmly. Select an appropriate spindle speed for the material being drilled and apply cutting fluid when machining stainless steel or other heat-sensitive alloys. Start drilling with light pressure to allow the split point to self-centre, then increase feed as the hole develops. Retract periodically to clear chips on deep holes.

Recommendations

The drill bit is intended for metalworking and plastics; use correct speeds and lubrication for stainless steels and hard alloys to extend tool life. Replace the bit if wear or chipping is observed to maintain hole quality and safety.
