## Long description

Drill bit set KWB 428040: a set of six precision-ground, cobalt-alloyed drill bits manufactured to DIN 338 standards. These right-hand cutting, type N bits have a 135° point angle, a bronze finish and a cross-cut self-centring tip to DIN 1412 C, supplied in an industrial-quality hanging box for storage and transport.
Advantages
The KWB 428040 drill bits are alloyed with 5% cobalt for improved heat resistance and wear life when machining hard or difficult materials. Precision grinding and a cross-cut tip provide accurate centring and reduced walking at drill start. The 135° split-point geometry and industrial finish ensure efficient chip removal and consistent drilling performance across a range of materials.
Suitable for
Alloyed and unalloyed steels
Stainless steels (V2A / V4A)
Grey cast iron and cast steel
Bronze and other non-ferrous metals
Plastics

How to use
Secure the appropriate drill bit in the drill chuck and ensure the workpiece is clamped. Use suitable cutting speed and feed for the material being drilled and apply cutting fluid when machining stainless steel or other heat-sensitive materials to extend tool life. Begin drilling with steady pressure; the cross-cut self-centring tip reduces walking and helps start holes accurately. Clear chips regularly and avoid excessive dwell at the bottom of holes.
Usage recommendations
For best results, select speeds and feeds matched to material and drill diameter, use coolant or lubricant for stainless steel and cast materials, and replace bits when wear degrades accuracy or increases cutting forces.
