Drill bit DeWalt DT4927-QZ, 80 mm, for metal, pack of 10

DeWalt DT4927-QZ drill bit, 80 mm length, pack of 10 is designed for drilling metal components with consistent, accurate results. This straight shank bit is intended for use with compatible handheld drills and drill presses. It is suitable for portable or stationary drilling of steels and other metals with high alloy content, delivering burr-free holes thanks to recessed cutting wings and a 'no-walk' tip that aids initial penetration and positioning.

Advantages

The solid construction and precision-ground geometry provide consistent hole sizes and extended life in metalworking applications. The 'no-walk' tip reduces the need for center-punching on surfaces 5 mm and above, improving start accuracy. Recessed cutting wings produce cleaner, more accurate, burr-free holes, reducing secondary finishing time. Supplied as a pack of 10, the set supports repetitive tasks and quick bit replacement on job sites or in workshops.

Suitable for

• Drilling steel plates and structural metal parts
• Working with high-alloy steels up to 1100 N/mm² tensile strength
• Sheet metal fabrication and repair
• Use with handheld drills and drill presses for production or maintenance

Key specifications

• Type: straight shank twist drill bit for metal
• Length: 80 mm
• Pack quantity: 10 pieces
• Tip design: no-walk tip for improved starting accuracy
• Cutting feature: recessed cutting wings for cleaner holes
• Suitable material: high-alloy steels and metals up to 1100 N/mm² tensile strength

How to use

Clamp the workpiece securely and select a suitable drill speed and feed for the metal being drilled. Fit the 80 mm straight shank bit into the chuck and ensure it is tightened. For surfaces 5 mm and above the no-walk tip assists accurate positioning; where necessary use coolant or cutting fluid to reduce heat and prolong bit life. Apply steady pressure and avoid excessive force; withdraw the bit periodically to clear chips when drilling deep holes. After use, clean and store the bits to prevent corrosion.

Usage recommendations

Use appropriate personal protective equipment, maintain correct drill speed for the material, and apply cutting fluid when drilling harder alloys. Replace bits when wear affects hole quality to maintain performance and safety.
