Drill bit Proline 70621 — metal HSS Ø6 mm, length 210 mm, 1 pc

Proline 70621 is a single high-speed steel (HSS) drill bit for metal with a 6 mm diameter and a total length of 210 mm. Supplied as one piece, it is intended for drilling metal and similar materials where extended reach is required. The drill bit is compatible with handheld drills and drill presses designed for long-reach metal drilling and provides accurate hole-making for repair, fabrication and installation tasks.

Advantages

The HSS material offers hardness and wear resistance suitable for cutting metal while maintaining edge sharpness. The 210 mm overall length enables drilling in deeper or hard-to-reach locations without the need for extension accessories. A single-piece supply simplifies selection and inventory for tasks requiring occasional long-reach holes. The 6 mm diameter provides a common, versatile size for fasteners and metalwork.

Suitable for

• Drilling holes in steel, iron and other ferrous metals
• Fabrication and assembly of metal components
• Maintenance and repair tasks requiring long-reach drilling
• Use with handheld drills and drill presses that accept long drill bits

Key specifications

• Material: High-speed steel (HSS)
• Diameter: 6 mm
• Total length: 210 mm
• Package quantity: 1 piece

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the chuck is tightened to prevent slippage. Mark the drilling point on the workpiece and, if necessary, use a center punch to prevent walking. Begin drilling at a low speed to establish the hole, then increase speed appropriate to the metal being drilled while applying steady, moderate pressure. Use cutting fluid or lubricant when drilling tougher metals to reduce heat and extend tool life. After drilling, withdraw the bit carefully while the spindle is stopped or at low speed to clear chips.

Usage recommendations

For best results when drilling metal, use appropriate cutting fluid, maintain correct drill speeds for the material, and replace the bit when wear or loss of cutting performance is observed. Ensure the drill and chuck are suitable for the 210 mm length and that safety measures such as eye protection and secure clamping of the workpiece are observed.
