Twist Drill Bit Set Bosch 2608577139

Impact Control HSS Twist Drill Bit Set Bosch 2608577139 contains high-speed steel (HSS) twist drill bits designed for reliable drilling in metals and other materials. The bits are precision-ground from solid HSS and feature an oxide-coated flute for improved surface quality and reduced wear. The shanks are compatible with a 1/4-inch hex-shank system, allowing use with drill drivers, impact drivers and drill stands.

Advantages

The set offers enhanced robustness for use with impact drivers, a durable solid HSS construction that resists breakage, and oxide-coated flutes that promote smoother cutting and longer tool life. Compatibility with a 1/4-inch hex-shank system ensures quick, secure bit changes and broad tool compatibility.

Suitable for

• Drilling alloyed and non-alloyed steel
• Working with cast steel and cast iron

How to use

Select the appropriate drill bit size for the material and pilot hole required. Secure the bit in a compatible 1/4-inch hex chuck or impact driver. Use appropriate cutting speed and steady feed pressure for the material being drilled; when drilling metal, apply cutting fluid or lubricant if needed to extend tool life and improve chip evacuation. Retract the bit periodically for deep holes to clear chips and avoid overheating.

Usage recommendations

For best results with the Bosch Impact Control HSS bits, use them with impact-capable drivers or drill drivers that accept 1/4-inch hex shanks, select the correct speed and lubrication for the workpiece, and replace worn bits to maintain drilling accuracy and safety.
