Metal Drill Bit Bosch HSS-G 11.0 x 94 x 142 mm for steel and metal

Bosch HSS-G 11.0 x 94 x 142 mm metal drill bit is a high-speed steel twist drill designed for creating precise round holes in steel and other ferrous and non-ferrous metals. The bit’s geometry and material deliver consistent cutting performance and wear resistance for workshop, maintenance and repair tasks. It fits standard drill chucks and is suitable for use with handheld drills and drill presses where a durable, general-purpose metal drilling solution is required.

Advantages

The HSS-G construction provides good heat resistance and preserves sharp cutting edges under typical metal-drilling speeds. The drill’s twist-flute design ensures efficient chip evacuation during drilling, reducing clogging and helping to maintain hole quality. Manufactured to Bosch quality standards, the bit offers repeatable performance and dimensional accuracy for through-holes and blind holes in metal parts.

Suitable for

• Drilling round holes in mild and alloy steels
• Workshop repairs and maintenance on metal components
• Use with handheld drills and drill presses
• General-purpose metalworking tasks requiring standard HSS bits

Key specifications

• Material: High-speed steel (HSS-G)
• Diameter: 11.0 mm
• Cutting length: 94 mm
• Total length: 142 mm
• Flute type: Twist flute for chip removal
• Shank type: Cylindrical shank for standard chucks

How to use

Secure the drill bit in a suitable chuck and tighten firmly before use. Mark the drilling point on the metal surface and, if needed, create a small center punch indent to prevent walking. Select an appropriate drill speed for the material and diameter, apply steady pressure and allow the bit to cut without excessive force. Use cutting fluid or lubricant for improved hole finish and extended tool life when drilling tougher steels. Clear chips periodically to avoid clogging and overheat.

Recommendations

For best results when drilling metal, use progressive pecking on deep holes, maintain correct spindle speed for an 11.0 mm HSS bit, and apply cutting lubricant on harder steels. Inspect the bit for wear and replace when edges become rounded or performance declines.
