Drill bit Proline 6.5 mm HSS model 5153685 for metal and general purpose

Drill bit Proline 6.5 mm HSS model 5153685 is a high-speed steel bit designed for drilling metal and general-purpose tasks. The solid HSS construction provides wear resistance and stable cutting performance, suitable for handheld and bench drills. The bit has a diameter of 6.5 mm, a working length of 63 mm and a total length of 101 mm, with a 135° point angle and adjustable helix for improved chip evacuation and precise hole formation.

Advantages

The Proline 6.5 mm HSS drill bit offers durable HSS material for extended life and consistent hole quality. Its 135° point angle reduces walking on the workpiece and improves centring when starting holes in metal. The adjustable helix angle enhances chip removal, lowering heat build-up and maintaining cutting efficiency during repeated drilling operations.

Suitable for (tasks / use cases)

• Drilling holes in mild and hardened metals
• Workshop and maintenance drilling tasks
• Handheld and bench drill applications
• General-purpose DIY projects requiring a 6.5 mm hole

How to use

Secure the drill bit in the chuck of a handheld or bench drill, ensuring it is centred and tightened. Select appropriate spindle speed and cutting lubricant for the metal being drilled—lower speeds and cutting fluid for harder metals, higher speeds for softer metals. Start drilling with light pressure to establish the centre, then apply steady feed until the hole is complete. Retract periodically to clear chips if necessary.

Usage recommendations

For best results when drilling metal, use cutting fluid, maintain a steady feed rate, and avoid excessive pressure to reduce heat and wear. Replace the bit if cutting performance declines or if the tip becomes damaged.
