Product Description

M35 Cobalt Tapered Shank Twist Drill Bit

High-Performance Cobalt HSS Taper Shank Drill for Metalworking

Product Overview

The M35 Cobalt Tapered Shank Twist Drill Bit is engineered for heavy-duty and high-precision metal drilling applications. Manufactured from M35 high-speed steel (5% cobalt), this drill bit offers exceptional hardness, heat resistance, and wear resistance, making it ideal for drilling stainless steel, alloy steel, cast iron, and other tough materials.

The tapered shank design provides a secure fit, increased rigidity, and stable power transmission—perfect for industrial machinery, lathes, and drilling equipment requiring reliable performance and long service life.

Key Features

Premium M35 Cobalt Steel (HSS-Co 5%)
- Excellent red-hardness and thermal stability
- Significantly longer lifespan than standard HSS drills
- Maintains sharpness under high-temperature drilling
- Ideal for difficult-to-cut materials
Tapered Shank for Enhanced Stability
- Provides superior rigidity and torque transmission
- Ensures steady drilling without slipping
- Suitable for large machine tools and industrial drilling setups
Precision-Ground Spiral Flutes
- Smooth chip evacuation
- Clean and accurate hole surface
- Reduced friction and improved drilling efficiency
118° or 135° Point Angle (Optional)
- Accurate centering and minimal wandering
- Suitable for general machining or high-hardness metals (135° recommended)
Industrial-Grade Durability
- Designed for long-term use
- Resists chipping, abrasion, and heat deformation
