## Summary description

Proline drill bit model 77705 — single metal drill bit with a diameter of 10.5 mm and overall length 340 mm. Designed for drilling metal and similar hard materials, supplied as one piece. Suitable for use with compatible drills for metalworking tasks, maintenance, and fabrication where a 10.5 mm hole is required.

## Long description

The Proline drill bit model 77705 is a single HSS metal drill designed for creating precise 10.5 mm holes. With an overall length of 340 mm, this extra-long, fully ground drill is intended for use in steel, non-ferrous metals and plastics. The bit is supplied as one piece and is suitable for compatible metalworking drills used in fabrication, maintenance and general workshop tasks where a long reach and accurate, straight holes are required.
Advantages
This drill bit features a 135° point angle with chamfering adjustment that enables quick penetration and reduces the need for extensive marking out. Fully ground flutes provide high accuracy and rectilinearity of holes, making the bit particularly useful when drilling with drill bushes or guides. Manufactured from refined high-speed steel (HSS), the bit combines hardness and toughness appropriate for cutting a range of metals and plastics. The extra-long length increases reach for deep or hard-to-access drilling operations.
Suitable for
Drilling through steel plates and structural components
Working with non-ferrous metals such as aluminium and brass
Drilling in plastics and composite materials
Deep-hole or hard-to-reach drilling where extra length is required
Use with drill bushes, jigs and fixtures for guided boring
Key specifications
Diameter: 10.5 mm
Overall length: 340 mm
Point angle: 135° with chamfering adjustment
Material: refined high-speed steel (HSS)
Finish: fully ground flutes for improved straightness and accuracy
Pack quantity: 1 piece
How to use
Secure the workpiece and, if required, use a drill bush or guide to ensure straightness. Select a compatible drill chuck and clamp the 10.5 mm shank firmly. Start drilling at low speed to establish the bore, then increase speed and apply steady pressure appropriate to the material. Use cutting fluid or coolant when working with steel or other metals to reduce heat and prolong tool life. Withdraw the bit occasionally to clear chips when drilling deep holes.
Usage recommendations
For best results when drilling metal, use an appropriate cutting lubricant, maintain stable clamping of the workpiece, and avoid excessive feed that can cause bit breakage. When drilling with guides or drill bushes, the fully ground geometry will help maintain hole accuracy; periodically inspect the bit for wear and replace it when the cutting edges become dull.
