Drill bit set DeWALT DT70758-QZ — 57 pcs, brad point and flat wood bits (3–12 mm specified)

DeWALT DT70758-QZ is a 57-piece wood drill bit set that combines brad point bits and flat (spade) wood bits in common sizes from 3 mm to 12 mm. The set is supplied in a medium tough case compatible with the TSTAK system and with connectable features for stacked storage and transport. Bits are designed for clean, precise holes in timber, including applications that encounter nails or fasteners, and the set includes accessories to support screw driving and fastener control.

Advantages

The included brad point bits feature a centring point, two shoulders and a peripheral cutting edge to deliver fast, accurate and clean drilling for dowel holes and through-holes. Flat wood bits are built with an extreme impact ready construction, a bevelled pilot point tip and bevelled outer cutting edges that ensure precise positioning and a clean exit even when drilling in timber with embedded nails. All bits have a thick, robust steel shank with a 1/4" profile for secure, slip-free clamping. The system case is connectable and stackable with TSTAK-compatible storage, and a small bulk storage case, screwdriver bits with optimised tip geometry, and a drive guide with extending sleeve are included to improve fastener stability and control.

Suitable for

• General carpentry and structural timber work
• Furniture making and joinery tasks such as dowel and through-hole drilling
• Site work where fast, clean wood holes are required, including drilling near nails or metal fasteners
• DIY projects requiring a range of common wood bit sizes from 3 mm to 12 mm

How to use

Select the correct bit size for the hole required and clamp the 1/4" shank securely in the drill chuck or quick-change holder. Use brad point bits when precise centring and clean edges are required, for example when drilling dowel holes or through-holes; use flat (spade) bits for fast removal of material when larger bore holes are needed. Operate the drill at appropriate speed for the bit size and timber type, apply steady pressure and allow the bit to cut without forcing. When encountering nails or metal fasteners, reduce speed and maintain control to protect cutting edges. Use the drive guide and screwdriver bits for fastener insertion and improved control where required.

Usage recommendations

Store the set in its connectable tough case and lock into your TSTAK storage for organised transport. Match drill speed to bit size and timber density, remove wood chips frequently to avoid clogging, and replace worn bits to maintain clean hole quality. When drilling near nails or screws, keep a controlled feed and lower speed to limit impact on the cutting edge.
