Metal drill bit Irwin TCT 6 mm — 1 pc

Irwin TCT 6 mm metal drill bit — single piece — is a tungsten carbide tipped twist drill designed for drilling precise 6 mm holes in a variety of metal materials. The TCT geometry and hard tip provide improved wear resistance and sustained cutting performance compared with standard high-speed steel bits. The bit is intended for workshop and professional use where repetitive drilling and dimensional accuracy are required.

Advantages

The tungsten carbide tip extends tool life and maintains sharpness under higher cutting loads. The TCT design ensures consistent hole quality and reduces the need for frequent resharpening. Robust construction limits chipping and deformation when used in common ferrous and non-ferrous metals. Supplied as a single piece it is suitable for direct replacement in standard drill chucks and straightforward to store and handle.

Suitable for

• Drilling 6 mm holes in steel and stainless steel
• Drilling in aluminum, copper and other non-ferrous metals
• Workshop and maintenance tasks requiring repeatable hole diameter
• Professional metal fabrication and assembly operations

Key specifications

• Tip material: tungsten carbide (TCT)
• Shank type: round shank for standard drill chucks
• Cutting diameter: 6 mm
• Intended material: ferrous and non-ferrous metals
• Quantity: 1 piece

How to use

Clamp the Irwin TCT 6 mm drill bit securely in a compatible drill chuck. Select an appropriate spindle speed for the target material — lower speeds for harder steels, higher speeds for softer non-ferrous metals — and apply steady feed pressure. Use cutting fluid or coolant when drilling harder or thicker metals to reduce heat and extend tip life. Withdraw the bit occasionally to clear chips and prevent clogging; inspect the tip regularly for wear or damage and replace if performance deteriorates.

Usage recommendations

For best results, match drill speed and feed to the material: use reduced RPM for stainless steels and increased coolant flow for prolonged runs. Avoid excessive side loads and bending moments; use center punches for accurate hole start and pilot drilling when necessary to maintain concentricity and extend tool life.
