## Summary description

Proline 77801 drill bit, single piece included. Designed as a standard drill accessory for creating holes in suitable materials. Supplied as one drill bit (1 pc), compatible with drills that accept the corresponding shank type and size. Useful for general drilling tasks in construction, woodworking or DIY repairs.

## Long description

Proline 77801 drill bit, single piece included. Designed for drilling clean, precise holes in metal, steel sheets and plastics, this HSS drill bit with titanium nitride coating offers improved wear resistance and sustained cutting performance. The roller shank provides secure grip in the drill chuck while the self-centring tip prevents wandering on rounded or slippery surfaces, ensuring accurate starts on oval or curved workpieces.
Advantages
The 4241 high-speed steel construction combined with a titanium nitride coating increases heat resistance and reduces friction, extending tool life. The design promotes rapid heat dissipation when working with harder materials, while the cutting geometry leaves hole edges clean and burr-free. The roller shank improves retention in the chuck and reduces slippage, and the self-centring point allows immediate, stable engagement on curved or polished surfaces.
Suitable for
Drilling holes in metal and steel sheets
Working with plastics and composite materials
General construction and workshop tasks
Woodworking and DIY repairs where metal or plastic fastenings are required
Key specifications
Material: 4241 high-speed steel (HSS)
Coating: titanium nitride (TiN)
Shank type: roller shank for improved chuck grip
Tip: self-centring geometry for rounded and slippery surfaces
Application: metal, steel sheets, plastics
Result: clean, burr-free hole edges and rapid heat dissipation
How to use
Install the drill bit securely in a compatible drill chuck designed to accept roller shanks. Select an appropriate rotation speed for the material being drilled — lower speeds for harder metals and higher speeds for plastics — and apply steady, even pressure without forcing the bit. Use cutting fluid or coolant when drilling thicker or harder metal sheets to improve heat control and tool life. Retract the bit periodically to clear chips when drilling deeper holes.
Usage recommendations
For best results, clamp workpieces firmly and mark drilling points clearly. Use appropriate personal protective equipment such as safety glasses and gloves. When drilling thin metal sheets, consider backing the material with sacrificial support to reduce distortion and achieve cleaner hole edges.
