Foret à pointer KWB 511909

The KWB 511909 Spur Drill Bit is a 9 mm FCE (brad point) HSS-M2 bit designed for precise wood drilling. It has a cylindric shaft, precision-ground flutes with TwinLand® groove design and a patented centring tip that reduces splintering and enables clean holes in hardwoods and soft materials. The bit is uncoated and supplied in blister packaging for convenient storage and handling.

Advantages

The precision-ground HSS-M2 construction provides industrial-quality hardness and dimensional accuracy. The TwinLand® groove design improves chip evacuation and reduces clogging during drilling. The patented centring tip and two taper taps ensure exact positioning and clean entry without ripping, particularly on dense decking timbers such as bangkirai and Douglas fir. The cylindric shaft fits standard chucks and the uncoated surface maintains predictable cutting behavior in wood and composite materials.

Key specifications

How to use

Secure the cylindric shaft in a compatible drill chuck. Select a drill speed appropriate for the material (lower speeds for hard woods, moderate speeds for soft woods and plastics). Position the centring tip on the marked spot and start drilling with steady pressure. Allow the TwinLand® grooves to evacuate chips and periodically withdraw the bit for chip clearing when drilling deep holes. After use, clean the flutes and store the bit in its blister packaging to protect the cutting edges.

Recommendations

For best results use lower rotational speeds and steady feed when drilling hardwood decking to avoid overheating and burning. Apply light lubrication or compressed-air chip clearing only when drilling plastics to prevent melting. Check compatibility with your drill chuck size before use.
