Drill bit GRAPHITE titanium-coated cylindrical 12 mm (57H162)

GRAPHITE titanium-coated cylindrical drill bit, 12 mm diameter (model 57H162) is designed for metalworking and general drilling tasks. The titanium coating increases surface hardness and reduces friction, which helps extend tool life and maintain cutting performance. The cylindrical shank fits standard chucks of handheld drills and drill presses, making the bit suitable for routine workshop operations in steel, non-ferrous metals and other common materials.

Advantages

The titanium coating improves wear resistance and reduces heat buildup during drilling, which contributes to more consistent hole quality and longer service life compared with uncoated bits. The 12 mm diameter provides a balance between rigidity and material removal rate for medium-sized holes. The cylindrical shank offers compatibility with a wide range of drill chucks and ensures easy mounting and stable rotation.

Suitable for

• Drilling holes in steel and structural metals
• Working with non-ferrous metals such as aluminum and brass
• General workshop tasks with handheld drills and drill presses
• Creating medium-diameter holes for fastening and assembly

Key specifications

• Drill type: twist drill bit with titanium coating
• Diameter: 12 mm
• Shank: cylindrical (straight) shank for standard chucks
• Intended materials: steel, non-ferrous metals, common workshop materials
• Surface treatment: titanium coating for increased hardness and reduced friction

How to use

Secure the drill bit in the chuck of a handheld drill or drill press, ensuring the bit is tightened and properly centered. Select a drilling speed appropriate for the material—lower speeds for harder steels, higher speeds for non-ferrous metals—and, if possible, use cutting fluid to reduce heat and improve chip evacuation. Apply steady, even pressure while drilling and allow the bit to clear chips periodically to avoid clogging and overheating. After use, clean the drill bit and store it in a dry place to prevent corrosion.

Usage recommendations

For best results, match drilling speed and feed pressure to the workpiece material and use cutting lubricant when drilling steels or other hard metals; replace the bit when cutting performance degrades significantly to maintain hole accuracy and reduce the risk of tool breakage.
