Precision Twist Drill 5997417 Taper Length Drill Bit 10mm

Product Description

The PRECISION TWIST DRILL 5997417 is a taper length drill bit from the QC91PM series, designed for heavy-duty metal drilling applications. Built from high-speed steel with a bright, uncoated finish, this bit features a 135-degree split point for improved self-centering and reduced walking on contact. A parabolic flute geometry promotes fast chip evacuation and reduced cutting resistance. The straight shank and tapered web configuration suit a wide range of drill chucks used in industrial and trade settings. Machinists, fabricators, and maintenance technicians working with ferrous and non-ferrous metals are the primary users of this tool.

This drill bit is suited for use in vertical mills, drill presses, and handheld drilling equipment where taper length geometry is required for deeper reach without sacrificing rigidity. The 10 mm diameter and 4-49/64-inch flute length make it appropriate for through-hole and deep drilling operations in production and job-shop environments. Material compatibility covers a broad range including alloy steel, carbon steel, stainless steel, cast iron, aluminum, brass, bronze, copper, titanium, magnesium, nickel, hardened steel, tempered steel, and graphite.

Key Features

• 135-degree split point for self-centering entry and reduced thrust
• Parabolic flute design for high-efficiency chip evacuation
• High-speed steel construction rated for heavy-duty cutting grades
• Tapered web with web thinning for reduced cutting resistance
• Right-hand cut, straight shank compatible with standard drill chucks
• Meets DIN 340 specification for taper length drill geometry

Compatibility

Designed as a DIN 340 taper length drill bit with a 10 mm straight shank, this bit fits standard drill chucks accepting a 0.3937-inch shank diameter. Suitable for use in drill presses, CNC drilling centers, and handheld power tools equipped with a keyed or keyless chuck of appropriate capacity.

Installation Notes

Install and remove this bit only with the machine at a full stop and power isolated. Secure the straight shank firmly in the chuck and verify concentricity before beginning a cut. Use appropriate cutting fluid or coolant for the workpiece material when drilling stainless steel, titanium, or hardened steel to extend tool life. Follow applicable shop safety standards and machine manufacturer guidelines for spindle speed and feed rate selection.
