Sumitomo 5VHY249 Solid Carbide Jobber Drill 13.70 Mm

Product Description

The SUMITOMO 5VHY249 is a solid carbide jobber-length drill bit designed for high-performance metal cutting in demanding industrial and machining applications. The drill measures 13.70 mm in diameter with an overall length of 176.00 mm and a flute length of 112.00 mm. It features a 135-degree split point geometry and a multi-layer TiAlCr/TiSi proprietary coating that improves wear resistance and heat management at the cutting edge. The straight cylindrical shank measures 14 mm in diameter with a shank length of 64 mm. This drill is used by machinists and tool-and-die professionals working in production environments where consistent hole quality and extended tool life are required.

The 5VHY249 is engineered for cutting steel, stainless steel, and hardened materials, corresponding to ISO workpiece material codes P, M, K, and S. The MDW-HGS series is built around a 5xD flute-to-diameter ratio and a tapered web configuration that supports aggressive chip evacuation. The drill includes through-coolant capability, making it well suited for deep-hole drilling operations on CNC machining centers where coolant delivery at the cutting zone is available. The h8 diameter tolerance on the drill body supports consistent fit in standard drill chucks and hydraulic toolholders.

Key Features

• Solid carbide construction for rigidity and heat resistance in hard material cutting
• Multi-layer TiAlCr/TiSi coating reduces friction and extends tool life in steel and stainless steel
• 135-degree point angle improves self-centering and reduces thrust force at entry
• Through-coolant design supports deep-hole drilling on coolant-equipped CNC machines
• Tapered web configuration promotes efficient chip evacuation in regular spiral flutes
• h8 shank diameter tolerance ensures consistent seating in standard toolholding systems

Compatibility

Designed for use in CNC machining centers and drilling machines equipped with through-coolant capability. Rated for primary workpiece materials including steel, stainless steel, and hardened materials (ISO codes P, M, K, S). Part of the SUMITOMO MDW-HGS series covering drill diameters from 12.50 mm to 15.00 mm.

Installation Notes

Installation and tool changes should be performed by a qualified machinist with the machine powered down and locked out per applicable safety procedures. The straight shank is compatible with standard drill chucks and hydraulic or shrink-fit toolholders rated for the 14 mm shank diameter. Verify coolant passages are clear and system pressure meets machine specifications before enabling through-coolant flow. Do not exceed the manufacturer-recommended feed and speed parameters for the workpiece material being cut.
