## Long description

Single Proline 77852K metal drill bit, diameter 5.2 mm and overall length 86 mm, designed for drilling steel and other metal surfaces. The solid, precision-ground body and 135° point angle with chamfering adjustment enable accurate centring and fast penetration. A titanium nitride coating increases tool life and improves the finish of drilled holes. Supplied as a single piece in retail blister packaging, this mid-sized drill bit is suitable for general metalworking, repairs and installation tasks that require a clean, consistent hole.
Advantages
The drill bit’s entirely ground construction ensures consistent geometry and concentricity for straight, reliable drilling. The 135° point angle with chamfering adjustment reduces walking on the workpiece and speeds up marking and penetration. Titanium nitride coating provides improved wear resistance and smoother chip evacuation, which helps maintain hole quality over repeated use. The compact overall length of 86 mm balances rigidity and reach for common workshop and onsite jobs.
Suitable for
Drilling holes in steel, cast iron and non‑ferrous metals
General metalworking and fabrication tasks
Repair, maintenance and installation work requiring a 5.2 mm hole
Workshop, construction site and home DIY projects

How to use
Secure the drill bit in a suitable chuck, ensuring tight clamping and correct alignment. Select an appropriate spindle speed and feed rate for the workpiece material; use slower speeds and steady pressure for harder metals. Apply cutting fluid or coolant when drilling steel to reduce heat and extend tool life. Start drilling with a centre punch or pilot mark to prevent slipping, then drill using steady, even pressure until the desired depth is reached. Withdraw the bit occasionally to clear chips and prevent clogging.
Usage recommendations
To maximise tool life and hole quality, use cutting fluid when drilling ferrous metals, avoid excessive feed rates that can cause overheating, and replace the bit when wear or damage becomes visible. Store the drill bit in its blister pack or a proper holder to protect the cutting edges.
