Drill bit GRAPHITE 57H112 titanium-coated cylindrical metal 1.5 mm, 5 pieces

GRAPHITE cylindrical metal drill bits, titanium-coated, 1.5 mm diameter, pack of 5 are designed for precise small-diameter drilling in metal and metal alloys. The titanium coating increases surface hardness and improves heat resistance, enabling longer tool life and stable cutting performance when making holes in thin sheets and light metal parts. These 1.5 mm bits fit standard straight-shank chucks on handheld drills and drill presses, making them suitable for detailed metalworking and electronics applications.

Advantages

The titanium coating provides improved wear resistance and better heat dissipation compared with uncoated bits, extending service life during frequent use. The cylindrical straight shank ensures secure clamping in standard chucks, reducing runout and improving hole accuracy. A consistent 1.5 mm diameter and precise ground cutting edges enable clean, accurate holes in thin metal sheets and small components. Supplied as a pack of five, the set offers immediate replacements for repetitive tasks.

Suitable for

• Drilling small-diameter holes in sheet metal and thin metal plates
• Creating mounting and access holes in electronics enclosures and panels
• Light fabrication tasks and model-making that require precise metal holes
• Use with handheld drills and bench drill presses for detailed work

Key specifications

• Drill type: cylindrical straight-shank metal drill bit
• Coating: titanium (improved hardness and heat resistance)
• Diameter: 1.5 mm
• Pack quantity: 5 pieces
• Suitable materials: steel, non-ferrous metals and metal alloys (thin sheets)

How to use

Secure the required drill bit in the drill chuck ensuring the shank is fully seated and tightened. Mark the drilling point on the workpiece and, when drilling thin metal, use a center punch to prevent slipping. Start at low to moderate speed and apply steady, moderate pressure; increase speed carefully if the drill and workpiece remain cool. Use cutting oil or lubricant for steel and harder alloys to reduce friction and extend bit life. Clear chips regularly and avoid excessive feed force that can cause bit breakage.

Usage recommendations

For best results when drilling metals, select appropriate cutting fluid, maintain moderate spindle speeds, and replace bits that show wear or chipping. Use a drill press for the most accurate holes; handheld drills are suitable for general-purpose and on-site work. Store bits in a dry place to preserve the coating and prevent corrosion.
