Sumitomo 5UHY017 Screw Machine Drill Bit 0.1417 in Carbide

Product Description

The SUMITOMO 5UHY017 is a solid carbide screw machine length drill bit designed for high-precision drilling in metalworking applications. Built to MDW-GS series specifications, it features a 135-degree split point angle and a straight-cylindrical shank with a diameter of 0.1575 inches (4.00 mm shank). The bit measures 0.1417 inches in diameter and 2.126 inches in overall length, with a flute length of 0.8268 inches and a maximum drilling depth of 0.6142 inches. Solid carbide construction provides the rigidity and heat resistance required for consistent performance in production drilling environments. This bit is installed by machinists and tool and die professionals working on precision metal components.

The 5UHY017 is suited for drilling cast iron and steel in screw machine and CNC machining center applications. Its screw machine length designation means a shorter overall length compared to jobber bits, providing improved rigidity and reduced deflection in close-tolerance work. The tapered web configuration and 2-flute design promote chip evacuation and help maintain hole quality across repeated cycles in production settings.

Key Features

• Solid carbide construction for rigidity and extended tool life in ferrous metal drilling
• 135-degree drill point angle for reduced thrust and self-centering entry
• Screw machine length for improved rigidity and reduced deflection
• 2-flute design with tapered web promotes efficient chip evacuation
• Straight-cylindrical shank compatible with standard drill chucks and collets
• Drill bit diameter tolerance h8 for consistent, repeatable hole sizing

Compatibility

Designed for use in cast iron and steel workpieces. Compatible with standard drill chucks and collets accepting a straight-cylindrical shank. Part of the SUMITOMO MDW-GS series; consult SUMITOMO tooling documentation for full series compatibility details.

Installation Notes

Installation and tool changes should be performed by qualified machinists following shop lockout and spindle-stop procedures before handling. Ensure the chuck or collet is properly torqued to the spindle before operation and that the shank is fully seated and secured. Carbide tooling is brittle and should not be dropped or subjected to side loading beyond the rated application. Verify spindle speed and feed rate are appropriate for the workpiece material and bit diameter before drilling.
