Drill bit GRAPHITE 57H122 titanium-coated metal drill, cylindrical shank 3.2 mm

GRAPHITE 57H122 titanium-coated metal drill, cylindrical shank 3.2 mm is a precision ground twist drill designed for drilling steel and a range of other metals. The titanium coating reduces friction and increases surface hardness, extending tool life while maintaining cutting performance. With a 3.2 mm cylindrical shank, this drill is compatible with hand-held drills and bench drill presses that accept that shank size, making it suitable for both workshop and maintenance tasks.

Advantages

The titanium coating improves wear resistance and heat dispersion, allowing for longer continuous drilling and reduced sharpening frequency. A precisely ground point ensures accurate centring and consistent hole diameter, while the cylindrical shank provides stable clamping in standard chucks. The combination of cutting geometry and surface treatment offers reliable performance when working with common construction and engineering metals.

Suitable for

• Drilling holes in mild and alloy steels
• Metalworking and fabrication tasks
• Maintenance, repair and assembly operations
• Use in hand drills and small drill presses

Key specifications

• Drill type: twist drill for metal
• Coating: titanium (Ti) surface treatment
• Material application: steel and other metals
• Shank style: cylindrical shank
• Shank diameter: 3.2 mm
• Drill diameter: 3.2 mm

How to use

Secure the drill bit in the drill chuck so the cylindrical shank is held firmly and runout is minimised. Select an appropriate cutting speed and feed for the metal being drilled; lower speeds are recommended for harder steels. Use a light cutting oil or coolant to reduce heat and prolong tool life, and apply steady pressure to maintain alignment without forcing the bit. After use, clean the bit of chips and lubricant and store it in a protective case to avoid damage.

Usage recommendations

For best results when drilling metals, start with a pilot hole for larger diameters, maintain correct spindle speed for the material, and use cutting fluid to reduce wear. Replace the bit when edge rounding or excessive runout is observed to preserve hole quality.
