## Summary description

Proline 77800 drill bit, single-piece set intended for general-purpose drilling in common materials. Supplied as 1 pc, suitable for use with handheld drills and drill presses for tasks such as creating holes in wood, soft metals and similar materials. Compact and compatible with standard drill chucks for repair, construction and DIY work.

## Long description

Proline 77800 drill bit is a single-piece general-purpose drill designed for drilling in common materials such as wood, soft metals, steel sheets and plastics. The cutting geometry and titanium nitride coating improve wear resistance and enable cleaner hole edges with reduced burr formation. The bit is supplied as one piece with a roller shank compatible with standard drill chucks, suitable for use in handheld drills and drill presses for repair, construction and DIY tasks.
Advantages
The drill bit is made from 4241 HSS and coated with titanium nitride to enhance hardness and prolong tool life. Its self-centring tip reduces walking on rounded and slippery surfaces, ensuring more accurate starts without the need for pilot holes. The design provides rapid heat dissipation during drilling in harder materials, while the cutting geometry keeps hole edges clean and largely burr-free. The roller shank offers secure grip in standard chucks and reduces slippage during operation.
Suitable for
 Drilling holes in wood for joinery, furniture assembly and repairs
 Drilling through soft metals and steel metal sheets for light fabrication and mounting
 Drilling plastics and composite materials for installation and prototyping
 General DIY tasks using handheld drills and drill presses
Key specifications
 Material: high-speed steel (type 4241 HSS)
 Coating: titanium nitride for increased wear resistance
 Shank type: roller shank for improved chuck grip
 Application: general-purpose drilling in wood, soft metals, steel sheets and plastics
 Features: self-centring tip, rapid heat dissipation, clean hole edges with minimal burr
How to use
Secure the Proline 77800 drill bit in a compatible chuck and ensure it is tightened to prevent slippage. Select a suitable spindle speed for the material: lower speeds for metals and higher speeds for wood and plastics. Apply steady, moderate pressure and allow the drill bit to do the cutting; avoid excessive force which can cause overheating or premature wear. For thicker or harder metal sheets, consider intermittent drilling to allow cooling. After use, remove metal chips and check the cutting edges for wear before storing.
Usage recommendations
Use cutting fluid or light oil when drilling metal to extend tool life and improve hole finish. For best accuracy on rounded or slippery surfaces, start drilling at low speed until the self-centring tip has established the pilot point. Replace the bit when signs of wear or chipping appear to maintain clean hole edges and consistent performance.
