Drill bit DeWalt DT4920 metal 61 mm, pack of 10

Solid drill bit DeWalt DT4920, length 61 mm, packed as a set of 10 pieces, designed specifically for drilling metal. The bit features a reinforced tip and precision-cut flutes that deliver stable rotation and efficient chip evacuation. It is compatible with standard drill chucks and intended for workshop and industrial applications requiring accurate, burr-free holes in sheet, plate and light structural components.

Advantages

The no-walk tip improves centring and makes initial penetration easier on a variety of metal surfaces 5 mm and thicker. Recessed cutting wings produce cleaner, more accurate holes with minimal burr formation. Hardened construction and ground geometry provide consistent cutting performance and extended life under repeated use. Supplied as a pack of 10 for convenience in production or maintenance environments.

Suitable for

• Portable and bench drilling of high-alloy steels and other metals
• Working with metal sheets and plates
• Light structural components and fabrication tasks
• Workshop maintenance and industrial drilling operations

Key specifications

• Length: 61 mm
• Application: designed for drilling metal
• Tip type: no-walk centring tip for easier penetration
• Cutting feature: recessed cutting wings for reduced burrs
• Pack quantity: 10 pieces
• Compatibility: suitable for standard drill chucks and both portable and stationary drills
• Material capability: suitable for metals up to tensile strength 1100 N/mm²

How to use

Select the appropriate drill speed and clamping method for the metal type and thickness; secure the workpiece to prevent movement. Fit the drill bit into a compatible chuck and ensure it is properly tightened and aligned. Begin drilling at moderate speed to allow the no-walk tip to locate; apply steady, even pressure and allow the bit to evacuate chips. For thicker or harder metals, use intermittent withdrawal to clear chips and reduce heat buildup. Use cutting fluid where appropriate to prolong tool life and improve hole quality.

Usage recommendations

Use cutting fluid for improved cooling and lubrication when drilling high-alloy steels. For best results on thin sheets, support the workpiece to reduce vibration and prevent distortion. Inspect bits for wear and replace when cutting edges become rounded or produce excessive burrs.
