Value Collection 01188705 No 70 Hss Jobber Drill Bit

Product Description

The VALUE COLLECTION 01188705 is a No. 70 wire-gauge jobber drill bit designed for precision drilling in ferrous and cast iron workpieces. Built from high speed steel (HSS) with an oxide coating for added surface protection, this bit features a 118-degree standard point angle and a right-hand spiral flute. The overall length is 1.25 inches with a flute length of 0.375 inches. A web-thinned, tapered web configuration reduces thrust at the cutting tip, making it well suited for small-diameter drilling where accuracy and clean entry are critical.

This bit is intended for general-purpose drilling applications in steel and cast iron, typical in light machining, toolroom work, and maintenance repair operations. The 0.0280-inch diameter corresponds to a No. 70 wire gauge size, making it appropriate for tasks such as drilling pilot holes, clearance holes, and small through-holes in metal components. It is sold individually but must be ordered in multiples of 12.

Key Features

• No. 70 wire gauge size at 0.0280-inch decimal diameter for precision small-hole drilling
• 118-degree standard point angle for reliable centering in steel and cast iron
• High speed steel construction provides hardness and wear resistance in metalworking applications
• Oxide coating adds surface protection and mild lubricity
• Web-thinned tapered web reduces cutting thrust and improves chip clearance
• Right-hand regular spiral flute for efficient chip evacuation

Compatibility

Designed as a general-purpose replacement or stock jobber drill bit for standard straight-shank drill chucks compatible with 0.0280-inch shank diameters, suitable for benchtop drill presses, hand drills, and CNC drilling applications in metalworking environments.

Installation Notes

Install in a drill chuck rated for the 0.0280-inch straight cylindrical shank, ensuring the chuck jaws seat evenly before tightening. Secure the workpiece firmly before drilling to prevent walking at this small diameter. Use appropriate cutting fluid when drilling steel to extend bit life and maintain dimensional accuracy. Do not exceed the recommended RPM range for this diameter when operating in ferrous materials.
