Precision Twist Drill 5995825 Jobber Drill Bit Hss

Product Description

The PRECISION TWIST DRILL 5995825 is a jobber-length twist drill bit in wire gauge size 3, equivalent to 0.2130 inches in diameter. Manufactured from M2 high speed steel with a bronze/purple coating, this bit features a 135-degree split point and web-thinned, tapered web construction for improved penetration and reduced walking on entry. The straight-cylindrical shank measures 0.2130 inches in diameter with a shank length of 1.25 inches. Overall length is 3.75 inches with a spiral flute length of 2.5 inches. Licensed HVAC, mechanical, and industrial trades installers use this bit for precision hole-making in ferrous and non-ferrous materials.

This drill bit is suited for general-purpose drilling in steel, stainless steel, cast iron, superalloys, and titanium. The Series HX18 designation places it within the HX10-HX15-HX18 product family, built to ANSI standards. It is appropriate for benchtop drill presses, hand drills, and CNC drilling operations where a standard jobber-length reach and 12xD flute-to-diameter ratio are acceptable for the required drilling depth. Coolant-through capability is not included in this configuration.

Key Features

• M2 high speed steel construction for durability in steel, stainless steel, cast iron, superalloys, and titanium
• 135-degree split point with web thinning reduces thrust and improves self-centering on hard materials
• Bronze/purple coating for surface protection and reduced friction during drilling
• Straight-cylindrical shank compatible with standard drill chucks
• Regular spiral flute geometry with 2-flute design for efficient chip evacuation
• Conforms to ANSI specification standards for consistent dimensional tolerances

Compatibility

Designed as an OEM-style jobber-length drill bit for use in standard drill chucks accepting a 0.2130-inch straight-cylindrical shank. Suitable for use across the HX10, HX15, and HX18 series applications per manufacturer designation.

Installation Notes

Installation is performed by machinists, pipefitters, electricians, and general trade technicians. Secure the shank fully in the drill chuck before operation and verify chuck key is removed prior to powering the tool. Do not exceed the recommended maximum drilling depth of 2.5 inches for this bit length. Use cutting fluid when drilling stainless steel, cast iron, or titanium alloys to extend tool life and manage heat buildup.
