Hertel 71206593 Jobber Drill Bit Size 42 Hss Oxide

Product Description

The HERTEL 71206593 is a jobber-length twist drill bit in wire gauge size 42, with a decimal diameter of 0.0935 inches. Manufactured from high speed steel with an oxide coating, it is built for general-purpose drilling in metal, wood, and plastics. The standard 118-degree split point promotes clean entry and reduces walking on flat surfaces. At 2.25 inches overall length with a 1.25-inch flute length, this bit is sized for benchtop drill presses, hand drills, and CNC applications where a compact jobber-length tool is required. Machinists, maintenance technicians, and fabricators install these in production and repair environments.

This bit suits light-duty drilling operations in ferrous and non-ferrous metals, plastics, and similar materials. The straight cylindrical shank seats in standard drill chucks without adapters. The regular spiral flute geometry provides efficient chip evacuation during through-hole and blind-hole drilling at typical feed and speed rates for HSS tooling. It is sold individually but requires a minimum order quantity of 12 units per purchase.

Key Features

• Wire gauge size 42 with 0.0935-inch decimal diameter for precise hole sizing
• High speed steel construction with oxide coating for corrosion resistance and reduced friction
• 118-degree standard point angle with web-thinned tip for reduced thrust and accurate starting
• Regular spiral flute with tapered web for consistent chip clearance
• Straight cylindrical shank fits standard drill chucks without adapters
• Right-hand cut for use with conventional clockwise-rotating spindles

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.0935-inch straight cylindrical shank, including benchtop drill presses, hand drills, and CNC machining centers.

Installation Notes

Installation and tool changes should be performed with the machine powered down and locked out per applicable safety procedures. Secure the shank fully in the drill chuck and tighten with a chuck key before operation. Do not exceed the recommended feed and speed ratings for HSS tooling in the workpiece material. Inspect the cutting edges for wear or chipping before each use and replace the bit if the point is damaged.
