Sumitomo 5UHY282 Solid Carbide Jobber Drill 16.00 Mm

Product Description

The SUMITOMO 5UHY282 is a solid carbide jobber-length drill bit engineered for high-performance metal cutting applications. It features a 16.00 mm diameter with a straight cylindrical shank and a 135-degree split point for accurate entry and reduced thrust. The multi-layer TiAlCr/TiSi proprietary coating delivers thermal resistance and wear protection needed when drilling steel, stainless steel, and hardened materials at elevated speeds. At 160.00 mm overall length with a 96.00 mm flute length, this drill belongs to the MDW-GS series and is built for demanding production environments where tool life and dimensional accuracy are critical.

This drill is suited for machining operations in shops handling structural steel, stainless alloys, and hardened workpieces. The 4xD flute-to-diameter ratio supports chip evacuation in moderate-depth holes without coolant-through capability, making it appropriate for wet or mist external coolant setups. Machinists and tool-and-die professionals working on CNC machining centers, drilling machines, or rigid setup mills are the primary users of this bit. The h8 diameter tolerance on the shank ensures consistent tool holder fit and minimal runout in precision boring and drilling cycles.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Multi-layer TiAlCr/TiSi coating provides thermal barrier and extends tool life in steel and stainless steel
• 135-degree drill point angle reduces entry thrust and improves self-centering on flat and curved surfaces
• Straight cylindrical shank with h8 tolerance ensures accurate seating in standard ER collets and drill chucks
• Tapered web configuration supports chip clearance and drill point strength through the cut
• 4xD flute-to-diameter ratio balances chip evacuation and flute stiffness for consistent hole quality

Compatibility

Designed for use with workpiece materials classified under ISO material codes K and P, covering steels, stainless steels, and hardened materials. Compatible with standard 16.00 mm straight-shank tool holders, ER collet chucks, and drill chucks accepting shank diameters in the 0.5000 to 0.6500 inch range. Part of the SUMITOMO MDW-GS series.

Installation Notes

Installation and operation should be performed by a qualified machinist familiar with carbide tooling and CNC or manual drilling equipment. Ensure the machine spindle and tool holder are clean and free of debris before seating the shank to maintain concentricity. Carbide drills are brittle compared to HSS — avoid interrupted cuts or side loading that can cause chipping or fracture. Follow the machine tool manufacturer and SUMITOMO MDW-GS series recommended speeds and feeds for the target workpiece material.
