Sumitomo 5VHY534 Solid Carbide Jobber Drill Bit 17mm

Product Description

The SUMITOMO 5VHY534 is a solid carbide jobber-length drill bit designed for high-performance metal cutting in demanding production environments. It features a 17 mm diameter with a straight-cylindrical shank and a 135-degree split point for accurate entry and reduced thrust. The dual TiAlCr and TiSi coating combination delivers elevated heat resistance and extended tool life when cutting abrasive or hard ferrous materials. With an overall length of 203 mm and a flute length of 136 mm, this bit belongs to the MDW-HGS series and is intended for use by machinists and CNC operators working in job-shop and production settings.

This drill bit is suited for cutting cast iron, stainless steel, and steel across a range of alloy grades. The 5xD flute-to-diameter ratio and coolant-through design make it a practical choice for deep-hole applications where chip evacuation and cutting temperature are critical. It is commonly used in CNC machining centers and drill presses where coolant delivery can be routed through the spindle. The MDW-HGS series is engineered for high-speed, high-feed drilling cycles where consistent hole quality and repeatable tool life are required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• Dual TiAlCr and TiSi coating for high-temperature performance and reduced built-up edge
• 135-degree drill point angle reduces entry thrust and improves self-centering
• Coolant-through design supports chip evacuation and thermal control in deep-hole drilling
• 5xD flute-to-diameter ratio provides extended reach without sacrificing chip flow
• Diameter tolerance h8 ensures consistent fit in standard drill chucks and hydraulic holders

Compatibility

Designed for use in CNC machining centers and drill presses capable of coolant-through spindle delivery. Rated for primary workpiece materials including cast iron (K), stainless steel (M), steel (P), and high-temperature alloys (S) per ISO material group classification.

Installation Notes

Installation and tool changes should be performed by qualified machinists with the spindle fully stopped and machine power locked out per shop safety procedures. Seat the straight-cylindrical shank fully in a compatible chuck or hydraulic tool holder to ensure concentricity and minimize runout. Verify coolant-through passages are clear and system pressure is set per machine specifications before beginning a drilling cycle. Do not exceed the tool manufacturer's recommended feed and speed parameters for the workpiece material being cut.
