Sumitomo 5VHY242 Carbide Drill Bit 13 Mm 135 Degree

Product Description

The SUMITOMO 5VHY242 is a solid carbide jobber length drill bit designed for high-performance metal cutting in demanding production environments. Built to MDW-HGS series specifications, it features a 13 mm diameter, a 135-degree drill point angle for self-centering entry, and a TiAlCr/TiSi dual-layer coating that extends tool life under high heat and abrasive conditions. Overall length is 167 mm (6.57 inches) with a 104 mm (4.09 inches) flute length. The through-coolant design allows cutting fluid delivery directly to the tip, making it well suited for deep-hole drilling and high-speed applications in ferrous materials. Licensed machinists and CNC operators are the primary users of this tool.

The 5VHY242 is engineered for cutting cast iron, stainless steel, and carbon steel workpieces, covering ISO material groups K, M, P, and S. Its 5xD flute-to-diameter ratio supports deep drilling passes with efficient chip evacuation. The straight-cylindrical shank fits standard drill chucks and collet holders without modification, making it compatible with CNC machining centers, drill presses, and manual lathes equipped for coolant-through tooling. This bit is a production-grade solution for shops running interrupted cuts or high-feed cycles on tough materials.

Key Features

• 13 mm (0.5118 inch) solid carbide construction for rigidity and heat resistance
• 135-degree split point reduces walking and cutting force at entry
• TiAlCr and TiSi dual coating improves wear resistance and thermal stability
• Through-coolant capable for deep-hole drilling and extended tool life
• 5xD flute-to-diameter ratio supports efficient chip evacuation in deep passes
• Tapered web configuration and h8 diameter tolerance for precise, repeatable holes

Compatibility

Designed for use in machining applications targeting cast iron, stainless steel, and steel workpieces (ISO material groups K, M, P, and S). Straight-cylindrical shank is compatible with standard drill chucks and collet systems accepting a 13 mm shank diameter.

Installation Notes

Installation and setup should be performed by a qualified machinist or CNC operator. Ensure the machine spindle is fully stopped and locked out before mounting or removing the bit. Verify coolant-through passages in the tool holder are clear and that system pressure matches the tool and application requirements. Inspect the cutting edge for chips or coating damage before each use and replace the bit if wear exceeds acceptable limits for the tolerance class.
