Screwdriver Bit KWB 704710 Hex 1/4" Drive 50mm Length

The KWB 704710 countersink bit is designed for creating precise countersinks in wood and non-ferrous metals. It features a seven-edged tip for accurate cutting, a 1/4" hexagonal shank for compatibility with drills and cordless screwdrivers, and a black oxide finish on tool steel for improved wear and corrosion resistance. Available head diameters are 10 mm, 13 mm and 16 mm, with a head length of 26 mm, a shank length of 24 mm and an overall length of 50 mm.

Advantages

The seven-edged tip ensures precise cuts and consistent countersink geometry. The 1/4" hex shank provides secure engagement and reliable power transmission with standard drill chucks and bit holders. Black oxide coating increases resistance to wear and corrosion, while the tool steel construction offers durability for repeated use.

Suitable for

• Countersinking screw heads in softwoods and hardwoods
• Creating recesses for screws in aluminium and other non-ferrous metals
• Use with cordless screwdrivers and drills with 1/4" hex bit holders

How to use

Install the 1/4" hex shank into a compatible drill or cordless screwdriver chuck. Position the countersink on the marked point and run the tool at low to medium speed to start the cut, increasing speed gradually if needed. Apply steady axial pressure and keep the tool perpendicular to the workpiece to achieve an even countersink. Withdraw the bit periodically to clear chips and inspect the recess depth.

Usage recommendations

For best results, use the 10 mm head for small screws and fine work, 13 mm for general-purpose countersinking, and 16 mm for larger screw heads. When working with metals, reduce speed and use light cutting oil if appropriate. Wear eye protection and follow safety instructions for power tools.
