## Long description

Twist drill bit Bosch HSS hex-shank 3.5 mm is a precision HSS drill designed for robust drilling in metal and suitable for general-purpose work in wood. The 3.5 mm diameter and 1/4-inch hex shank provide secure retention in impact drivers and standard chucks. The bit is precision-ground from solid high-speed steel with an oxide-coated flute and a 135° split-point tip for accurate centring and reduced walking.
Advantages
The HSS material and precision grinding deliver long tool life and consistent hole quality. The oxide-coated flute reduces wear and improves chip removal. A 135° split-point prevents walking and enables active cutting from the first contact. The 1/4-inch hex shank ensures quick bit changes and stable grip in impact drivers and hex chucks.
Suitable for
 Drilling holes in metal (thin to medium thickness)
 Drilling in wood and composite materials
 Use with impact drivers and cordless drills with 1/4-inch hex chucks

How to use
Clamp the bit in the drill or impact driver so the hex shank seats fully. Start drilling at low speed to establish the hole, then increase speed appropriate to the material. Apply steady, moderate feed pressure and allow the drill to cut without forcing. Withdraw periodically to clear chips when drilling deeper holes in metal. Use suitable cutting fluid when drilling metals to reduce heat and extend bit life.
Usage recommendations
For best results in metal, pilot the hole when drilling thicker sections and use cutting oil. Replace the bit if wear or chipping appears at the tip. Store the bit in its blister pack or a dedicated case to protect the cutting edges.
