## Summary description

Proline 77802 drill bit, single-piece set containing one drill bit. Intended for drilling tasks compatible with standard drills; suitable for DIY and light professional work where a single replacement or specific size bit is required. Compact packaging makes it convenient to carry and store with other drill accessories.

## Long description

Proline 77802 — 1 piece drill bit is a single HSS cutting tool designed for precise drilling in metal, steel sheets and a variety of plastics. The bit combines a titanium nitride coating and a roller shank to improve wear resistance, heat dissipation and compatibility with standard drills. Compact packaging makes it convenient for storage and transport with other drill accessories and for carrying a dedicated replacement bit for maintenance or one-off tasks.
Advantages
The high-speed 4241 HSS substrate provides durability and consistent cutting performance in harder materials, while the titanium nitride coating reduces friction and extends tool life. Self-centring geometry prevents the drill from slipping on rounded or slippery surfaces and maintains clean, burr-free hole edges. The roller shank improves grip in the chuck and facilitates fast bit changes. The design also promotes rapid heat dissipation during sustained drilling operations.
Suitable for
Drilling holes in metal sheets and thin steel components
Working with various plastics requiring clean hole edges
DIY repair and maintenance tasks where a single precise bit is needed
Light professional work in workshops, construction and metal fabrication
Key specifications
Material: high-speed steel (4241 HSS)
Coating: titanium nitride (TiN)
Shank type: roller shank for improved chuck grip
Suitable materials: metal, steel sheets, plastics
Feature: self-centring tip for rounded and slippery surfaces
Hole quality: clean, burr-free edges
How to use
Mount the drill bit securely in a compatible chuck, ensuring the roller shank seats properly for stable gripping. Use appropriate drill speed and cutting fluid when working with steel or other hard materials to aid heat dissipation and prolong bit life. Apply steady axial pressure and allow the bit to cut without excessive force; the self-centring tip is designed to prevent walking on curved or slippery surfaces. After use, clean chips from the flutes and store the bit in its compact packaging or a suitable holder.
Usage recommendations
For best results when drilling steel sheets and hard plastics, start at a lower speed to establish the hole, then increase speed within the drill's and bit's recommended range. Use cutting oil when working with steel to reduce wear and improve finish; inspect the bit for wear before reuse and replace if the coating is compromised or edges are blunt.
