Hertel 71206874 Jobber Drill Bit Wire 70 Hss Oxide

Product Description

The HERTEL 71206874 is a jobber-length drill bit designed for general-purpose drilling in metal, wood, and plastics. Built from high speed steel with an oxide coating for reduced friction and improved chip evacuation, this bit cuts at 118 degrees and measures 1.25 inches overall length with a 0.375-inch flute length. Wire size 70 corresponds to a decimal diameter of 0.0280 inches, making it suited for fine-hole work in light-gauge materials. The straight-cylindrical shank seats securely in standard drill chucks. Two spiral flutes with a regular helix and tapered web configuration promote clean cutting and consistent hole quality across a range of materials.

This bit fits common production, maintenance, and toolroom applications where small-diameter precision holes are required. Wire gauge sizing is standard in instrument manufacturing, electronics assembly, light fabrication, and sheet metal work. The web-thinned point reduces entry force on thin-gauge stock. At 0.0280 inches diameter, this bit is appropriate for tasks such as pilot holes, through-holes for small fasteners, and fixture work. It is sold individually per package with a minimum order of 12 pieces, suitable for stocking in shop crib environments or field service kits.

Key Features

• Wire size 70 diameter at 0.0280 inches for fine-hole drilling applications
• 118-degree standard point angle for general-purpose material entry
• High speed steel construction provides durability across common shop materials
• Oxide coating reduces friction and helps extend cutting edge life
• Web-thinned, tapered web design lowers thrust requirements at entry
• Straight-cylindrical shank for secure chuck retention in standard keyed or keyless chucks

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with any standard drill chuck accepting a 0.0280-inch straight-cylindrical shank, including benchtop drill presses, hand drills, and CNC toolholders configured for small-diameter straight-shank tooling.

Installation Notes

Installation is performed by machinists, toolroom technicians, maintenance mechanics, and production floor operators. Secure the shank fully in the chuck and verify runout before drilling. Use appropriate cutting fluid or lubrication when drilling ferrous metals to extend tool life. Do not exceed the recommended feed and speed range for the workpiece material and bit diameter to avoid breakage at this small diameter.
