## Long description

Set of two Proline HSS-TiN drill bits with 4.8 mm diameter, designed for general-purpose drilling in metal, wood and some plastics. The bits feature a 135° split-point geometry with adjustable clearance for precise centering and reduced walking. Blanks are ground and finished with a titanium nitride (TiN) coating to increase wear resistance and improve hole surface quality. Working length is 52 mm and overall length 86 mm.
Advantages
Titanium nitride coating extends tool life and improves cutting performance compared with uncoated high-speed steel. The 135° split-point angle with rake adjustment minimises walking and helps start holes accurately on metal surfaces. Ground flutes and balanced geometry produce cleaner holes and consistent drilling results across different materials. The 4.8 mm diameter is suitable for common pilot and fastener holes.
Suitable for
Drilling holes in metal sheets and structural components
General woodworking tasks and pilot holes
Drilling some plastic materials
Home DIY and workshop use with standard drill chucks

How to use
Clamp the appropriate Proline HSS-TiN 4.8 mm bit securely in a standard drill chuck. Use suitable cutting speed and feed for the material: lower speeds for metal, moderate speeds for wood and plastics. Apply steady pressure and keep the drill perpendicular to the workpiece. For metal drilling, use cutting fluid or lubrication to reduce heat and prolong bit life. Clear chips periodically to maintain cutting efficiency.
Usage recommendations
Store bits dry and protected to avoid corrosion. Replace bits when wear or chipping reduces hole quality. Match drill speed and lubrication to the workpiece material to maximise life of the TiN-coated HSS bits.
