Foret hélicoïdal KWB 258625

Spiral cutting drill bit KWB 258625 is a high-speed steel (HSS M2) spiral drill sharpened for right-hand rotation with a cylindrical shank. The drill has a 130° point angle with a special polished section and a specially polished spiral with "Quick Cut" geometry for forming small swarf. A reinforced core and spiral shoulder plus a specially shaped short spiral notch make the tool extra robust and heat-resistant. It is developed for optimal cutting performance, particularly in all types of stainless steel, and is also suitable for all steel grades, cast iron and cast steel. The single-piece construction provides durability for use with cordless and corded drilling machines.

Advantages

The KWB 258625 drill offers a reinforced core and spiral shoulder for improved strength, a Quick Cut polished spiral for efficient swarf control, and a 130° point angle for precise centering and reduced walking. Its extra robust design and high heat resistance enable longer tool life during demanding stainless steel and general metal drilling. The cylindrical shank and single-piece HSS M2 construction ensure consistent performance with both cordless and tethered machines.

Key specifications

How to use

Mount the KWB 258625 drill securely in the chuck of a cordless or corded drilling machine. Select appropriate speed and feed for the material being drilled (lower speeds for stainless steel and hard alloys). Use steady pressure and allow the drill to cut without excessive force. For deep holes or prolonged drilling, retract periodically to clear swarf. Apply coolant or cutting fluid when drilling stainless steel to reduce heat and extend tool life.

Recommendations

For best results in stainless steel, use reduced spindle speeds, moderate feed, and consistent coolant flow. Inspect the drill for wear and replace when performance or hole quality declines.
