Hertel C.E96.S60-3 Cobalt Drill Bit Set Wire 1-60

Product Description

The HERTEL C.E96.S60-3 is a 60-piece cobalt screw machine length drill bit set covering wire gauge sizes 1 through 60, with diameters ranging from 0.04 inches to 0.228 inches. Each bit is manufactured from cobalt high-speed steel with a bright, uncoated finish and features a 135-degree split-point tip that reduces walking on contact and allows drilling to begin without a center punch. Straight shanks fit standard drill chucks. The shorter screw machine length body provides increased rigidity over jobber-length bits, making this set well suited for high-production or precision drilling in hard and abrasive materials. Bits are stored in a metal case indexed by wire gauge size.

This set is used in metalworking, maintenance, and fabrication environments where a full range of wire gauge sizes must be on hand. Screw machine length geometry reduces deflection in drill press and milling machine applications and in tight-clearance hand drilling situations. Cobalt construction handles stainless steel, high-alloy steels, cast iron, and other hard materials that would wear standard HSS bits prematurely. The set is appropriate for machine shops, industrial maintenance crews, and skilled tradespeople requiring a compact, complete wire gauge drill index.

Key Features

• 60-piece set covering wire gauge sizes 1 through 60 (0.04 to 0.228 inches)
• Cobalt high-speed steel construction for drilling hard and abrasive materials
• 135-degree split-point tip reduces walking and eliminates the need for center punching
• Screw machine length body provides greater rigidity and reduced deflection vs. jobber length
• Bright, uncoated finish compatible with cutting fluids and coolants
• Metal indexed storage case keeps bits organized by wire gauge size

Compatibility

Designed for use in standard drill chucks and drill press spindles accepting straight shank bits across the 0.04 to 0.228 inch diameter range.

Installation Notes

Secure the bit firmly in the chuck before operation and verify the chuck key is removed prior to powering the drill press or hand drill. Use appropriate cutting fluid or coolant when drilling stainless or high-alloy steel to extend bit life and manage heat buildup. Inspect each bit for chipping or wear before use, and follow shop safety practices including eye protection and secure workpiece clamping.
