Drill bit set Proline 10809, 2 pcs, length 100 mm

Proline 10809 drill bit set contains two 100 mm drill bits designed for situations where a defined drill length and consistent hole quality are required. The set is intended for general-purpose drilling in woodworking, plastics and light metals, and is compatible with standard drills and drill drivers. The 100 mm length helps achieve controlled drilling depth and repeatable results when working on assemblies or parts that require a specific penetration.

Advantages

The drill bits provide consistent cutting performance and straightness over their 100 mm length, which supports accurate depth control during repetitive tasks. Their design reduces the need for frequent repositioning when drilling through thicker workpieces or layered materials. The set format of two bits offers a simple backup option to maintain workflow and minimise downtime when one bit becomes worn or blunt.

Suitable for

• General woodworking tasks requiring controlled hole depth
• Drilling in plastic components and assemblies
• Light metal drilling where standard-speed drills are used
• Workshop and on-site repair jobs needing repeatable hole placement

Key specifications

• Set contents: 2 drill bits
• Overall bit length: 100 mm
• Application materials: wood, plastics, light metals
• Intended use: general-purpose drilling with drills and drill drivers
• Design focus: controlled drilling depth and consistent hole quality

How to use

Select a drill or drill driver compatible with the bit shank and secure the bit in the chuck according to the tool manufacturer’s instructions. Mark the drilling position and, if exact depth is required, set a depth stop or use a piece of tape on the bit at the required depth. Start drilling at low speed to establish the hole, then increase speed as appropriate for the material. Maintain steady axial pressure and back the bit out periodically when drilling deeper holes to clear chips and reduce heat buildup.

Usage recommendations

Use appropriate cutting speeds and avoid excessive feed force to prolong bit life. For plastics and soft woods, use lower speeds and gentle pressure to prevent melting or splintering. When drilling light metals, ensure lubrication or coolant is applied where recommended and clamp workpieces securely to prevent movement.
