Irwin IR73825 Jobber Drill Bit 25/64 in 3/8 in Shank

Product Description

The IRWIN IR73825 is a jobber-length twist drill bit designed for general-purpose drilling in metal, wood, and plastic. It features a 25/64-inch cutting diameter paired with a 3/8-inch reduced shank, allowing it to fit standard three-jaw drill chucks without requiring a full-size chuck capacity. The bright finish indicates an uncoated high-speed steel construction, suited for lower-heat applications and materials where a specialty coating is not required. This bit is a standard trade-shop consumable used by electricians, plumbers, HVAC technicians, and general contractors for everyday hole-making tasks in both field and shop settings.

The IR73825 fits into typical jobber-length drilling applications where moderate hole depth is needed. The reduced 3/8-inch shank makes it compatible with mid-range corded and cordless drills that accept 3/8-inch chucks, which are common on job sites across all trades. Its jobber-length geometry provides a practical balance between reach and rigidity for through-hole and clearance-hole work in light structural and mechanical applications.

Key Features

• 25/64-inch cutting diameter for precise hole sizing in metal, wood, and plastic
• 3/8-inch reduced shank fits standard 3/8-inch drill chucks
• Jobber-length geometry balances reach with bit rigidity
• Bright finish uncoated construction suited for general-purpose drilling
• Sold individually — single-piece unit of measure

Compatibility

Designed as a general-purpose jobber-length drill bit compatible with 3/8-inch and larger keyed or keyless drill chucks on standard corded and cordless drills.

Installation Notes

Secure the reduced shank fully into the chuck jaws before tightening to prevent slippage under load. Use appropriate drilling speed for the material being drilled — lower RPM for harder metals, higher RPM for wood and plastics. Eye protection is required during all drilling operations per standard job-site safety practices. Inspect the cutting edges for wear before each use and replace when the bit no longer cuts cleanly to avoid overheating or workpiece damage.
