Sumitomo 5VHY162 Solid Carbide Jobber Drill Bit 5 Mm

Product Description

The SUMITOMO 5VHY162 is a solid carbide jobber-length drill bit designed for high-performance metal cutting in demanding shop and production environments. It carries a dual TiAlCr and TiSi coating that extends tool life when drilling ferrous and abrasive materials. The 135-degree split-point geometry reduces thrust and improves self-centering on entry, minimizing the need for a center punch in most setups. With a 5 mm diameter, 98 mm overall length, and straight-cylindrical shank, it fits standard drill chucks and collet systems without modification. Coolant-through capability supports high-speed drilling cycles where chip evacuation and heat management are critical. Licensed machinists, tool-and-die techs, and CNC operators are the primary installers.

This drill bit is built for production drilling in cast iron, stainless steel, and carbon steel. It belongs to the MDW-HGS series, which is engineered for 5xD depth-to-diameter drilling in ISO material groups K, M, P, and S. Typical applications include CNC machining centers, gang drilling operations, and precision manual drilling where hole tolerance and surface finish matter. The h8 diameter tolerance on the shank ensures consistent runout in precision tool holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive workpiece materials
• TiAlCr and TiSi dual coating improves heat resistance and extends cutting life in ferrous materials
• 135-degree drill point angle reduces entry thrust and improves self-centering
• Coolant-through design supports chip evacuation and thermal control at depth
• 5xD flute-to-diameter ratio allows drilling to 44 mm flute depth in a single pass
• Tapered web configuration with 2-flute geometry optimizes chip flow in steels and cast iron
• h8 shank diameter tolerance ensures low runout in precision collet and chuck systems

Compatibility

The SUMITOMO 5VHY162 is rated for primary workpiece materials classified under ISO codes K (cast iron), M (stainless steel), P (carbon and alloy steel), and S (high-temperature alloys). It is part of the MDW-HGS series and is sized for standard 5 mm tool holders and collet chucks.

Installation Notes

This tool is intended for installation by qualified machinists or CNC setup technicians. Before mounting, verify that the tool holder or collet is clean and within specification to maintain runout within acceptable limits. When using coolant-through capability, confirm that spindle coolant pressure and flow rate are set per machine specifications before beginning a drilling cycle. Do not exceed the recommended cutting parameters for the workpiece material group, as solid carbide tooling is brittle and susceptible to breakage from deflection or interrupted cuts without proper setup.
