Metal drill bit Irwin TCT 5 mm, 1 pc

Irwin TCT 5 mm metal drill bit is a single-piece, tungsten carbide-tipped cutting tool designed for drilling through steel, non-ferrous metals and metal alloys. The TCT (tungsten carbide tip) construction provides increased wear resistance and sustained cutting performance during both manual and machine drilling operations. This 5 mm diameter bit is intended for producing precise round holes where repeatable accuracy and edge life are important.

Advantages

The Irwin TCT 5 mm drill bit combines a hardened body with a tungsten carbide tip to extend service life and reduce wear when cutting metal. Its geometry is optimized for efficient chip removal and reduced heat buildup, supporting stable drilling at moderate speeds. The single-piece design and precise diameter control ensure consistent hole size and alignment in workshop and industrial applications.

Suitable for

• Drilling holes in carbon steel and alloy steel
• Piercing thin and medium-thickness non-ferrous metals (aluminium, brass, copper)
• Maintenance and repair tasks requiring accurate 5 mm holes
• Machine drilling and hand drill use in workshops

Key specifications

• Diameter: 5 mm
• Tip material: tungsten carbide (TCT)
• Intended material: steel, non-ferrous metals, metal alloys
• Pack quantity: 1 piece

How to use

Secure the workpiece firmly to prevent movement and select an appropriate drill speed for the material being cut—lower speeds for harder steels, higher speeds for softer non-ferrous metals. Use a suitable lubricant or cutting fluid when drilling steel to reduce heat and prolong tip life. Center punch the drilling location if accurate positioning is required, then start drilling with light feed until the tip establishes a pilot, increasing feed to maintain steady cutting. Clear chips periodically to avoid clogging and overheating.

Usage recommendations

For best results, match drill speed and feed to the workpiece: use slower speeds for hardened steels, higher speeds for aluminium. Apply cutting fluid for steel and heavier alloys; minimal or no lubricant is acceptable for soft non-ferrous metals. Inspect the tip for wear before use and replace the bit when cutting performance or hole accuracy degrades.
