Heavy-Duty M35 Cobalt DIN345 Taper Bit – Ideal for Cast Iron, Pipe, Beams, and Plates
The XRTOOLS M35 DIN345 Taper Shank Drill Bit is an industrial-grade cutting tool engineered for deep-hole, high-precision drilling in demanding materials like stainless steel, cast iron, and alloy steel. Manufactured from M35 high-speed cobalt steel (5% Co), this bit delivers exceptional hardness, red hardness, and abrasion resistance for long service life—even in high-temperature drilling applications.
Designed in strict accordance with DIN 345 standards, it features a Morse taper shank (MT1–MT5), allowing for direct, chuck-free installation in lathe tailstocks, radial drill machines, and boring mills.
Each M35 DIN345 bit is fully ground and CNC-milled to ensure high dimensional accuracy and consistent performance:
| Element | Detail |
|---|---|
| Manufacturing | CNC Milling & Precision Flute Grinding (fully ground body) |
| Material | M35 Cobalt HSS (5% cobalt) – superior heat & wear resistance |
| Point Design | Standard 118° point angle or optional 135° split point |
| Cutting Edge | Chisel edge with web thinning for reduced feed pressure |
| Flute Design | Straight flute with deep spiral groove for optimal chip ejection |
| Shank Type | Morse Taper (MT1 to MT5) with precise taper per DIN345 specs |
| Runout Tolerance |
Strict concentricity for vibration-free drilling |
This optimized geometry ensures fast centering, low cutting resistance, and accurate bore alignment, especially for large-diameter holes and deep-hole applications.
The M35 DIN345 taper shank drill is ideal for use in:
| Industry | Application Examples |
|---|---|
| Metal Fabrication | Drilling baseplates, steel frames, I-beams, and thick sections |
| Machining & Lathes | Center hole and deep boring in carbon steel, stainless, and hardened steels |
| Shipbuilding / Rail | Precision drilling in cast housings, weldments, and structural plates |
| Maintenance & Repair | Equipment retrofitting and bolt hole creation in heavy steel assemblies |
| Tool & Die Making | Boring holes in tool steel and alloy materials for dies, jigs, and press tooling |
Compatible with manual feed and CNC-controlled machines, this bit is perfect for professional workshops, machining centers, and heavy industry environments.
