Sutton 1mm R40 Inox Jobber Drill Bit - DIN338 - HSS TiAlN

Sutton Tools Inox Jobber Drills are an industrial quality drilling solution specially designed for superior performance in stainless steel. Tailored to overcome the difficult-to-machine material properties of stainless steel, Inox drill bits have a fast spiral, short flute and unique stepped core design providing a smooth and effortless cutting action never before seen. For added wear resistance, these drill bits feature the latest generation Futura Nano PVD coated tip. Inox drill bits have been independently tested to achieve 70% more tool life in stainless steel compared to standard drill bits. Available through AIMS Industrial Supplies, these tools meet the exacting demands of Australian tradespeople, engineers, and maintenance teams who need quality cutting tools they can depend on shift after shift.

Where this tool is used

• General purpose drilling operations in ferrous and non-ferrous metals, plastics and composite materials.
• Machine-shop and on-site hole-making with handheld drills, drill presses and CNC machining centres.
• Production and maintenance environments where consistent hole quality and tool life are critical.

Key specifications

Selecting the right option

Manufactured from HSS, this range offers an excellent balance of toughness and wear resistance suited to general-purpose production and maintenance work. The TiAlN Tip surface treatment reduces friction, improves chip evacuation and extends service life compared with uncoated tools — particularly valuable in harder or abrasive materials. The 130°° point angle is optimised for the materials and applications this range is designed for. Match the drill diameter to your required hole size and ensure adequate feed rate and coolant for best results. Maximum cutting depth is rated at 3xD — keep within this limit to maintain hole quality and avoid overloading the tool.
