## Summary description

Wera 05104633001 is a countersink drill bit with a 1.24 cm diameter intended for drilling and creating countersinks. Designed for use with compatible drills, it combines a cutting tip and countersink geometry to produce a clean entry and a recessed head seat. Suitable for tasks requiring precision hole finishing and countersinking in joinery and metalwork where this diameter is required.

## Long description

Wera 05104633001 is a 1.24 cm diameter countersink drill bit designed for drilling, deburring and creating precise 90° countersinks. The tool features a 3-flute cutting geometry with a combined drill and countersink profile that produces a clean entry hole and a recessed seat for fastener heads. Manufactured to close tolerances, the bit provides reliable chip evacuation and reduced tilting during operation, and it is intended for use with compatible 1/4" hex shank holders that accept D 6.3 take-up.
Advantages
The 3-cutter design follows DIN 335-C geometry at a 90° angle, delivering consistent countersink profiles and smooth chamfering. Material elasticity and heat-treated finishing increase durability while maintaining cutting performance. Optimized flute geometry helps evacuate chips efficiently, reducing clogging and keeping the working surface cleaner. The 1/4" hex shank enables quick insertion and secure retention in standard bit holders, ensuring stable operation and minimal wobble.
Suitable for
 Drilling and countersinking pilot holes in metal
 Deburring and chamfering edges on workpieces
 Joinery operations requiring a 90° countersink for flat fastener heads
 General workshop and maintenance tasks with compatible drills and holders
Key specifications
 Countersink diameter: 1.24 cm
 Cutter geometry: 3-flute, 90° countersink profile
 Suitable shank type: 1/4" hex for secure holder engagement
 Primary functions: drilling, deburring, chamfering, countersinking
 Chip evacuation: optimized flute design for efficient removal
How to use
Secure the countersink bit in a compatible holder or drill chuck that accepts a 1/4" hex shank. Mark and center the workpiece where the hole and countersink are required. Start drilling at low to moderate speed to establish the entry hole, then apply steady pressure while widening the opening to form the 90° countersink profile. Withdraw periodically to clear chips and check the fit of the fastener head. For best results, use cutting speeds and feeds appropriate to the workpiece material and avoid excessive axial force that could cause tilting.
Usage recommendations
Use cutting fluid when working with metals to reduce heat and extend tool life. For softer materials, test on a scrap piece to determine optimal speed and feed. Inspect the bit regularly for wear or chipping and replace when the cutting edges become rounded to maintain clean countersinks and safe operation.
