Precision Twist Drill 5997141 Jobber Drill Bit 19/32 in

Product Description

The PRECISION TWIST DRILL 5997141 is a jobber-length drill bit designed for general-purpose drilling in metal and hard materials. Sized at 19/32 inch (0.5938 inch decimal), it features a 135-degree split-point tip geometry with web thinning for reduced thrust and faster entry into the workpiece. The parabolic-style spiral flute promotes efficient chip evacuation during deep-hole operations. Built from high-speed steel with a bright uncoated finish, this bit is suited for use by machinists, maintenance technicians, and metalworking tradespeople operating drill presses, magnetic base drills, or handheld power tools.

This bit is rated for drilling into steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium under its QC21P series classification. The straight cylindrical shank accepts standard drill chucks without modification. With a flute-by-diameter ratio of 9xD and a maximum drilling depth matching the 5-3/16 inch flute length, it handles deep-hole drilling applications without requiring excessive pecking cycles. It is a right-hand cut bit and does not require coolant-through capability for typical shop applications.

Key Features

• 135-degree drill point angle with web-thinned tip for reduced entry force
• High-speed steel construction rated for steel, stainless steel, cast iron, non-ferrous metals, superalloys, and titanium
• Parabolic spiral flute geometry supports efficient chip clearance in deep holes
• Straight cylindrical shank compatible with standard drill chucks

Compatibility

Designed as an OEM-style jobber-length drill bit suitable for use in standard drill chucks across drill presses, magnetic base drills, and handheld power tools configured for straight-shank bits in the 0.5000 to 0.6500 inch diameter range.

Installation Notes

Installation is performed by machinists or maintenance technicians familiar with metalworking equipment. Secure the straight shank fully in the drill chuck and verify concentricity before drilling. Power down and de-energize the drill press or tool before changing bits. Do not exceed the rated flute depth of 5-3/16 inches when establishing maximum drilling depth in a single setup.
