Drill bit Proline 2 mm titanium-coated cylindrical for metal, 2 pcs (model 77820)

Proline 2 mm titanium-coated cylindrical drill bits for metal, pack of 2, are designed for precision drilling in steel and other metals. These solid-shank bits feature a cylindrical shank and a titanium nitride coating that increases surface hardness and wear resistance. The 2 mm diameter provides fine, accurate holes for metalworking and maintenance tasks and is compatible with standard chucks on handheld drills and drill presses.

Advantages

The titanium coating reduces friction and extends tool life compared with uncoated high-speed steel bits. The cylindrical shank ensures secure clamping in keyless and keyed chucks, while the small 2 mm diameter allows for controlled, accurate starts and reduced material deformation. Supplied as a twin pack, these bits provide a spare for continuous work or backup for routine maintenance.

Suitable for

• Drilling small-diameter holes in steel, stainless steel, and non-ferrous metals
• Metalworking on handheld drills and drill presses
• Maintenance, repair, and assembly tasks requiring precise pilot holes
• Workshop tasks where extended bit life and repeatability are needed

Key specifications

• Diameter: 2 mm
• Coating: titanium nitride (titanium-coated)
• Shank type: cylindrical (solid shank)
• Quantity: 2 pieces per pack
• Material compatibility: steel, stainless steel, and other metals

How to use

Select the appropriate drill speed for the metal type and clamp the cylindrical shank securely in the drill chuck. Mark the drilling point and, if required, use a center punch to prevent wandering. Use a steady feed and moderate pressure; apply cutting fluid or lubricant when drilling harder steels to improve chip evacuation and reduce heat. Withdraw the drill bit periodically to clear chips and avoid overheating.

Usage recommendations

For best results, start with a small pilot hole when drilling thick or hard metals, keep the bit cool with cutting fluid, and replace the bit when increased drilling forces or poor surface finish indicate wear.
