16.5mm Roll Forged HSS Morse Taper Shank Drills Bit For Metal Steel
DIN345 Taper Shank Drill Bit – Morse Taper, HSS/M35 for Metal, Cast Iron & Structural Steel
The XRTOOLS DIN345 Taper Shank Drill Bit is a precision-ground, heavy-duty twist drill designed to meet DIN 345 industrial standards. Featuring a Morse taper shank (MT1–MT5), it provides a secure, self-locking fit directly into machine spindles and lathe tailstocks—eliminating the need for a chuck.
Made from HSS or M35 cobalt steel, this drill bit is engineered to deliver outstanding drilling performance in tough materials like carbon steel, stainless steel, alloy steel, cast iron, copper alloys, and more. With options for various surface treatments, this tool is tailored to meet the demands of machine shops, steel fabrication, heavy equipment repair, and precision manufacturing across the U.S. and Russian markets.
Key Application Scenarios
| Industry / Machine Use | Typical Application Examples |
|---|---|
| Lathe Machines (MT Tailstock) | Direct mounting for accurate deep-hole drilling into shafts, bars, and plates |
| Radial Drill Machines | Large-diameter hole making in steel columns or mechanical components |
| Milling Machines | Precise borehole operations on alloy or tool steel workpieces |
| Welding & Fabrication Shops | Pre-drilling for bolted joints or weld prep in I-beams and plates |
| Shipbuilding & Heavy Industry | Structural drilling in cast components and machine frameworks |
Whether you are fabricating a steel bridge or boring through a 2" thick gearbox plate, this bit ensures smooth entry, centered holes, and long-term reliability.
Surface Treatment Options
| Finish Type | Benefits |
|---|---|
| Bright Finish | For non-ferrous metals; clean cutting, lower cost |
| Black Oxide | Increased wear resistance, reduces friction and corrosion |
| Titanium Nitride (TiN) | Gold coating improves tool life, heat resistance, and chip flow |
| TiAlN (Titanium Aluminum Nitride) | For dry cutting, high-speed applications in hardened steels |
| Steam Tempered | Dark blue finish improves lubricity and bonding of coolant |
Surface finish can be selected depending on target material and feed speed requirements.
