Precision Twist Drill 5997213 Taper Length Drill Bit No. 32

Product Description

The PRECISION TWIST DRILL 5997213 is a taper length, high-speed steel (HSS) drill bit engineered for demanding metal-cutting applications. It carries a No. 32 wire gauge size, equivalent to 0.1160 inches in diameter, with a 135-degree split point that reduces walking and lowers feed pressure at start. The parabolic flute geometry evacuates chips aggressively, making it well suited for deeper holes where standard flute designs tend to pack. This bit runs bright and uncoated, with a straight cylindrical shank and a flute-to-diameter ratio of 6xD. It is installed and used by machinists, tool-and-die workers, maintenance mechanics, and fabricators working in shop or field environments.

This drill bit is rated for general-purpose heavy-duty use across a broad range of metallic and non-metallic materials. Confirmed material applications include alloy steel, aluminum, aluminum alloy, brass, bronze, carbon steel, cast iron, copper, graphite, hardened steel, magnesium, magnesium alloy, malleable iron, nickel, stainless steel, steel, tempered steel, titanium, and titanium alloy. The taper length body provides additional reach compared to a jobber-length bit, making it a practical choice when working in recessed or deep-clearance setups. The self-centering split point eliminates the need for a center punch in most applications on flat stock.

• Taper length body at 2.75 inches flute length and 5.125 inches overall length for extended reach
• High-speed steel construction, bright and uncoated, suited for a wide range of ferrous and non-ferrous materials
• Conforms to ANSI standards; heavy-duty grade classification

Compatibility

Designed as a general-purpose taper length drill bit compatible with any standard drill press, CNC machining center, or hand drill with a chuck capacity accommodating a 0.1160-inch straight shank. No specific OEM system compatibility is stated by the manufacturer for this part number.

Installation Notes

Install in a properly sized chuck and verify the shank seats fully and runs true before operation. Use appropriate cutting fluid or coolant for the material being drilled, particularly when working with stainless steel, titanium alloys, or hardened steel. Ensure the workpiece is securely fixtured to prevent rotation or movement during drilling. Inspect the cutting edges before each use and replace the bit if chipping or excessive wear is observed.
