Precision Twist Drill 5995780 Wire 2 Jobber Drill 135 Hss

Product Description

The PRECISION TWIST DRILL 5995780 is a high-speed steel jobber-length drill bit designed for general-purpose and heavy-duty drilling applications. It carries a wire gauge size of 2, corresponding to a decimal diameter of 0.2210 inches. The 135-degree split-point geometry reduces walking on entry and lowers thrust force compared to standard 118-degree points. A bronze straw coating provides light lubricity and heat resistance during drilling. The two-flute regular spiral design evacuates chips efficiently. Overall length is 3.875 inches, with a flute length of 2.625 inches. The bit weighs approximately 0.04 pounds. HSS M2 material grade gives it solid wear resistance across a wide range of workpiece materials.

This drill bit is rated for use in high-temp alloys and general metalworking applications, with a primary workpiece material code covering ferrous, non-ferrous, and heat-resistant alloy categories (P, M, K, S). It is suited for production drilling in machine shop environments, maintenance and repair operations, and field use where precise small-diameter holes are required. The straight cylindrical shank fits standard drill chucks without adapters. Series HX10-HX15-HX18 designation covers the full family this bit belongs to within the PRECISION TWIST DRILL line.

Key Features

• 135-degree web-thinned split point reduces thrust and minimizes bit walk on entry
• M2 high-speed steel construction for heat and wear resistance in heavy-duty drilling
• Bronze straw coating adds lubricity and extends tool life in abrasive or high-temp alloy materials
• Regular spiral flute with tapered web promotes consistent chip evacuation
• Straight cylindrical shank at 0.3125 inches diameter fits standard keyed and keyless chucks
• ANSI-standard geometry ensures dimensional consistency and interchangeability

Compatibility

Part of the PRECISION TWIST DRILL HX10-HX15-HX18 series. Designed as a direct replacement or replenishment bit for setups requiring wire gauge size 2 (0.2210 inches) jobber-length drill bits with a straight shank and 135-degree point.

Installation Notes

Install in a properly rated drill chuck and verify shank seating before operation. Ensure the workpiece is securely clamped before drilling to prevent rotation or movement. Power down the machine and release all stored energy before changing bits or adjusting chuck position. Follow applicable shop safety standards and manufacturer feed-and-speed guidelines for the specific workpiece material being drilled.
