Cylindrical Drill Bit Smart 6 x 100/60 mm by Smart

Cylindrical Drill Bit Smart 6 x 100/60 mm by Smart is a general-purpose drilling tool designed for precise through and blind holes. The bit has a 6 mm diameter shank, a total length of 100 mm and a working length of 60 mm, making it suitable for handheld drills and drill presses. It is intended for use in wood, many plastics and soft metals where material and machine compatibility permit, offering a straightforward solution for construction, renovation and DIY tasks.

Advantages

The solid cylindrical design provides stable centring and reduced runout when used in standard chucks. A 60 mm working length delivers sufficient engagement for common drilling depths while the 100 mm overall length allows access in recessed or partially obstructed areas. Compatibility with both handheld drills and drill presses makes the bit versatile for on-site and workshop use. The 6 mm diameter is a common size for fixtures, dowels and pilot holes, enabling straightforward replacement and interchangeability.

Suitable for

• Drilling through and blind holes in wood
• Drilling in many plastics
• Light drilling in soft metals such as aluminium and brass where appropriate cutting speed and lubrication are used
• Use with handheld electric drills and drill presses for construction and renovation
• DIY projects requiring 6 mm holes for fasteners, dowels or pilot holes

Key specifications

• Shank/diameter: 6 mm
• Total length: 100 mm
• Working length: 60 mm
• Tip type: standard twist drill geometry suitable for general-purpose drilling
• Intended materials: wood, plastics, soft metals (subject to machine and material compatibility)
• Suitable mounting: standard drill chucks on handheld drills and drill presses

How to use

Select appropriate rotational speed and feed rate for the target material and secure the workpiece to prevent movement. Fit the 6 mm cylindrical shank into a properly tightened chuck and confirm concentricity before starting. For wood and plastics, a moderate speed and steady pressure are normally sufficient; for soft metals, reduce speed, use cutting lubricant if required and apply light, steady pressure to avoid overheating. Withdraw the bit occasionally when drilling deep holes to clear chips and improve cooling.

Usage recommendations

For longer tool life and clean holes, clamp workpieces, use a backing board when drilling through, and adapt speed and lubrication to the material being drilled. Inspect the bit for wear or damage before use and replace when dull to maintain drilling accuracy.
