## Long description

DeWalt DT70789-QZ is a single 12 mm drill bit intended for general-purpose drilling in wood and metal where material and drill type are compatible. The bit has a standard straight shank for secure clamping in hand drills and drill drivers and is designed to deliver a reliable 12 mm hole quickly and with consistent performance for both professional and DIY tasks.
Advantages
The 12 mm diameter offers a common, versatile hole size for fittings, fasteners and through-holes. A standard shank ensures compatibility with most chucks, making the bit easy to change and suitable for a wide range of drilling tools. The single-bit format allows replacement or use as a spare without purchasing multipacks.
Suitable for
 Drilling 12 mm holes in timber and softwoods
 Drilling through thin sheet metal and metal fittings where material thickness and bit type permit
 Installing bolts, dowels or conduit requiring a 12 mm clearance hole
 General-purpose workshop and on-site drilling with hand drills and drivers
Key specifications
 Diameter: 12 mm
 Intended materials: wood, metal (depending on thickness and drill speed)
 Shank type: straight/standard shank for chuck clamping
 Package: single drill bit
How to use
Secure the bit in the drill chuck, ensuring it is centered and tightened. Select an appropriate drill speed and feed rate for the material: lower speeds for metal and higher for most woods. Use cutting lubricant when drilling metal if recommended for the material and thickness. Apply steady pressure, withdraw occasionally to clear chips, and finish the hole with controlled feed to avoid oversizing.
Usage recommendations
Match drill speed and lubrication to the material, clamp the workpiece securely, and inspect the bit for wear before use. Replace the bit if cutting performance declines to maintain hole accuracy and reduce risk of breakage.
