Sumitomo 5VHY182 Carbide Drill Bit 7mm 135 Deg

Product Description

The SUMITOMO 5VHY182 is a solid carbide jobber length drill bit designed for high-performance metal cutting applications. It measures 7 mm in diameter (0.2756 inches) with a 135-degree drill point angle and an overall length of 109 mm (4.2913 inches). The bit carries a dual TiAlCr and TiSi coating that resists heat and wear during demanding cuts. Two flutes with a tapered web configuration evacuate chips efficiently. The straight-cylindrical shank seats securely in standard drill chucks. This bit is sized and specified for use by machinists, tool-and-die tradespeople, and CNC operators working with ferrous and specialty metals.

The 5VHY182 belongs to the MDW-HGS series and is engineered for cutting cast iron, stainless steel, and steel. The 5xD flute-to-diameter ratio supports deeper hole entry while maintaining rigidity. The drill point length is 1.45 mm (0.0571 inches), and the flute length is 56 mm (2.2047 inches). With coolant-through capability, this bit supports internal coolant delivery for temperature control in high-speed or production drilling environments. It is suited to both manual and CNC machine tool setups where consistent hole quality in hard materials is required.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard-metal applications
• TiAlCr and TiSi dual coating provides heat resistance and extended tool life
• 135-degree split point angle reduces walking and cutting force at entry
• Coolant-through design supports internal coolant delivery for thermal management
• 5xD flute-to-diameter ratio enables deeper hole drilling with stable chip evacuation
• Tapered web configuration strengthens the core while maintaining cutting efficiency

Compatibility

Designed for metal cutting in cast iron, stainless steel, and steel workpieces. Compatible with standard straight-cylindrical shank drill chucks accepting 7 mm (0.2756 inch) shanks. Part of the Sumitomo MDW-HGS series.

Installation Notes

Installation and use should be performed by qualified machinists or CNC operators familiar with carbide tooling. Ensure the machine spindle and chuck are fully stopped before loading or removing the bit. Carbide tooling is brittle and should not be dropped or struck against hard surfaces. When using the coolant-through feature, verify that coolant pressure and flow rate are within the machine tool specifications before initiating a cut.
