## Summary description

Bosch HSS-Co 135 drill bit, cobalt high-speed steel construction with 135° tip angle, 11.5 mm diameter and 94 mm overall length. Designed for drilling metals and hard materials, suited to hand drills and drill presses with straight shank mounting. Provides wear resistance and edge retention for industrial and workshop applications.

## Long description

Bosch HSS-Co 135 straight shank drill bit, 11.5 mm diameter and 94 mm overall length, is manufactured from cobalt-alloyed high-speed steel and features a 135° split point tip. The tool is intended for drilling through steel, stainless steel and other hard materials where increased heat resistance and cutting-edge stability are required. The straight shank design fits standard chucks on hand-held drills and drill presses, offering reliable concentricity and compatibility with workshop equipment.
Advantages
The cobalt-alloyed HSS construction improves wear resistance and maintains sharpness under higher temperatures compared with standard HSS bits. The 135° tip reduces walking when starting holes, enabling more accurate positioning and faster penetration in dense materials. The straight shank and precise machining provide stable mounting in chucks, while the overall geometry balances cutting efficiency and hole finish quality for industrial and professional workshop use.
Suitable for
 Drilling mild and hardened steels
 Work on stainless steel and other corrosion-resistant alloys
 Metalworking tasks on drill presses and hand drills
 Repair, maintenance and fabrication in shops and industrial settings
Key specifications
 Material: cobalt-alloyed high-speed steel (HSS-Co)
 Tip angle: 135° split point
 Diameter: 11.5 mm
 Overall length: 94 mm
 Shank type: straight shank for standard chucks
 Suitable for drilling into steels, stainless steels and other hard materials
How to use
Secure the drill bit in the chuck and ensure it is clamped concentrically to avoid runout. Select an appropriate cutting speed and feed for the material being drilled; use lower speeds and steady pressure for harder alloys. Apply cutting fluid or coolant when drilling stainless steel or other heat-sensitive metals to reduce friction and extend tool life. Start the hole at low speed to ensure the split point locates correctly, then increase speed as the cut stabilizes. Clear chips regularly to prevent clogging and overheating.
Usage recommendations
For best performance, use a suitable cutting lubricant, maintain correct spindle speeds according to material hardness, and replace the bit when wear affects hole diameter or surface finish. Inspect the shank and cutting edges before use to ensure safe, precise drilling.
