Vrták Single KWB 512005 5 mm šesťhranný

Drill Bit Single KWB 512005 5 mm Hexagonal is a 5 mm HSS-M2 hardwood drill bit with an adjustable counterbore and countersink, designed for pre-drilling and clean fixing installation in decking and garden furniture. The tool features a ball-bearing counterbore that stops rotating when it contacts the workpiece to prevent marking of the wood and a 1/4" hexagon shank to ISO 1173, E 6.3 for secure fit in hex chucks and bit holders.

Advantages

The HSS-M2 steel construction provides durability and accuracy when drilling hardwoods such as Bangkirai as well as softwood. The adjustable counterbore and countersink deliver consistent bore and countersink depth on every fixing. The ball-bearing counterbore prevents surface damage by stopping rotation on contact, and the 1/4" hexagonal shank ensures firm seating in compatible tools.

How to use

Secure the drill bit in a compatible 1/4" hex chuck or bit holder. Adjust the counterbore and countersink to the required depth for your fixing. Drill the pilot hole at the marked position with steady pressure; the ball-bearing counterbore will stop rotating when it contacts the wood, preventing surface marking. Check the bore and countersink depth and adjust as needed before final fixing.

Recommendations

Use appropriate drilling speed and steady feed for hardwoods like Bangkirai to avoid overheating. Keep the bit sharp and clean; replace if worn to maintain accurate bore and countersink depths. Wear eye protection and follow standard safety practices when drilling.
