Lh Dottie HS11C 11/64 Inch Jobber Length Drill Bit Hss

Product Description

The LH DOTTIE HS11C is an 11/64 inch jobber-length drill bit designed for heavy-duty drilling applications in trade and industrial settings. Made from M2-grade high-speed steel (HSS) with a black and gold finish, it features a 135-degree split-point tip that self-centers on contact, eliminating the need for a center punch. The four-flute design paired with a heavy-duty web construction delivers added strength and resistance to deflection during use. Laser-etched size markings remain legible through repeated use. Electricians, plumbers, and general contractors reach for this bit when drilling through metal, wood, and similar materials in day-to-day service work.

The HS11C fits standard drill chucks and rotary tools that accept a flatted shank. Its 3.25 inch overall length and 3/16 inch flute length make it well-suited for jobber-length drilling tasks in tight or moderate-clearance locations. The 11/64 inch diameter is a common pilot and clearance size for fasteners and conduit anchors, making it a frequent grab in electrical and mechanical rough-in work. The black and gold finish provides mild corrosion resistance during storage and repeated handling on the job site.

Key Features

• M2-grade HSS construction for extended cutting life in metal and wood
• 135-degree split-point tip self-centers without a center punch
• Four-flute heavy-duty web design resists deflection and breakage
• Laser-etched size markings for fast, reliable identification
• Flatted shank prevents bit slippage in chuck during high-torque drilling
• Black and gold finish provides surface protection during storage

Compatibility

Designed as a jobber-length replacement or stock drill bit compatible with standard 3-jaw drill chucks and rotary tools that accept a flatted shank in the 11/64 inch size class.

Installation Notes

Secure the flatted shank firmly in the chuck before drilling to prevent slippage under load. Use appropriate cutting fluid or lubrication when drilling through ferrous metals to extend bit life and reduce heat buildup. Allow the bit to cool between extended drilling cycles to avoid premature dulling of the HSS cutting edges. Follow applicable workplace safety standards and wear appropriate eye protection when operating rotary drilling equipment.
