Broca helicoidal HSS Bosch Impact Control 2608577130

Impact Control HSS Twist Drill Bits by Bosch (2608577130) are high-speed steel twist drills designed for metalworking and general-purpose drilling. Precision-ground from solid HSS with an oxide-coated flute, these drill bits provide a smooth cutting surface and increased wear resistance. The bits accept a 1/4-inch hex shank for secure use with drill drivers, impact drivers and drill stands, and are suitable for alloyed and non-alloyed steel, cast steel, cast iron, sintered iron, non-ferrous metals, sheet metals and plastics.

Advantages

The HSS construction combined with precision grinding ensures consistent drilling accuracy and longer tool life. The oxide-coated flute improves surface quality and reduces friction and wear during cutting. The 1/4-inch hex shank enables rapid bit changes and reliable retention in impact drivers and drill chucks. The drill bit geometry is optimised for metal and hard material applications, providing robust performance under impact-driver conditions.

Suitable for

• Drilling alloyed and non-alloyed steel
• Drilling cast steel, cast iron and sintered iron
• Drilling non-ferrous metals and sheet metal
• Drilling plastics and general workshop tasks

How to use

Secure the twist drill bit in the tool's chuck or quick-change holder compatible with a 1/4-inch hex shank. Select an appropriate speed and feed rate for the material being drilled; lower speeds are recommended for harder steels and higher speeds for softer metals and plastics. Use cutting lubricant when drilling steel to reduce heat and prolong bit life. Apply steady pressure and allow the drill to cut without excessive force; withdraw occasionally to clear chips when drilling deep holes.

Recommendations

Use with compatible impact drivers or drill stands. For best results on steel, apply cutting oil and moderate speed; for non-ferrous metals and plastics, higher speeds and light lubrication are acceptable. Replace the bit if excessive wear or chipping appears to maintain accuracy and safety.
