L H Dottie Co HS29 High Speed Steel Drill Bit 29/64 Inch

Product Description

The L H DOTTIE CO HS29 is a 29/64-inch high speed steel drill bit designed for boring clean, accurate holes in metal, wood, and other common trade materials. High speed steel construction provides the hardness and heat resistance needed to maintain a sharp cutting edge through repetitive use. This bit is sold individually and suits the drilling demands of electricians, HVAC technicians, plumbers, and general contractors who require a reliable, mid-sized bit for field and shop work.

The HS29 fits standard 3/8-inch and 1/2-inch keyed or keyless chucks found on corded and cordless drills common to the trades. It is well suited for tasks such as drilling pilot holes for conduit hangers, pipe supports, cable routing, and structural fasteners in light-gauge steel, aluminum, and wood framing. Its 29/64-inch diameter is frequently used where a close-tolerance hole is needed before tapping threads or seating hardware.

Installation Notes

Always secure the workpiece before drilling to prevent rotation and ensure a clean hole entry. Use appropriate cutting fluid or lubricant when drilling through metal to extend bit life and reduce heat. Electricians and other trade professionals should follow OSHA hand and power tool safety guidelines when operating drills on the job site. Inspect the bit for cracks or dullness before each use and replace if the cutting edges are damaged.
