Hertel 02387975 Reduced Shank Drill Bit 1-3/64 in Hss

Product Description

The HERTEL 02387975 is a reduced shank twist drill bit designed for drilling into low and medium tensile strength materials. The bit features a 1-3/64 inch (1.0469 inch decimal) cutting diameter paired with a 1/2 inch straight-cylindrical shank, allowing it to seat in standard 1/2 inch drill chucks despite the larger cutting diameter. Constructed from high-speed steel with an oxide finish, the bit runs a standard 118-degree point angle and a right-hand spiral flute. Overall length is 6 inches with a 3 inch flute length. This tool is suited for metalworking, fabrication, and general mechanical trades where oversized holes are required without a matching large-capacity chuck.

This drill bit is intended for use in drill presses, magnetic drills, or heavy-duty hand drills equipped with a 1/2 inch chuck. It is commonly applied in HVAC, plumbing, and electrical rough-in work where larger pilot or clearance holes are needed through structural steel, mild steel, iron, and similarly rated low to medium tensile strength materials. The reduced shank design makes a larger cutting diameter accessible on standard shop and field equipment. No coolant system is required for this bit.

Key Features

• Reduced 1/2 inch shank allows use in standard 1/2 inch chucks with a 1-3/64 inch cutting diameter
• High-speed steel construction provides durability across repeated drilling cycles in metal
• 118-degree standard point angle suitable for general-purpose metal drilling
• Oxide finish improves lubricity and corrosion resistance during use
• Right-hand cut with regular spiral flute for consistent chip evacuation
• 3 inch maximum drilling depth supports typical structural and plate stock applications

Compatibility

Designed as a general-purpose reduced shank drill bit compatible with any 1/2 inch chuck drill press or hand drill. Best suited for low and medium tensile strength materials including mild steel, iron, and similar stock.

Installation Notes

This bit is installed and serviced by machinists, fabricators, and trade mechanics using standard drill equipment. Always secure the shank fully in a properly tightened 1/2 inch chuck before use. Ensure the workpiece is clamped or fixtured to prevent rotation during drilling. Inspect the cutting edges for wear before each use and replace the bit if chipping or dulling is observed.
