Eagle Cutting Tool 1090-114-I Hss Silver Deming Drill Bit

Product Description

The EAGLE CUTTING TOOL 1090-114-I is a high-speed steel (HSS) Silver Deming drill bit designed for heavy-duty drilling in metal, wood, and plastic. Silver Deming bits feature a reduced 1/2 inch shank, allowing the 1-7/32 inch cutting diameter to be chucked in standard 1/2 inch drill presses and portable drills. This import-grade bit is suited for production drilling, maintenance shops, and fabrication environments where larger-diameter holes are required without specialty tooling. Machinists, maintenance technicians, and fabricators use this style of bit regularly for through-hole and spot-facing work.

This drill bit is well-suited for use in machine shops, HVAC fabrication, plumbing rough-in, and general metalworking applications where a 1-7/32 inch diameter hole is required. The 1/2 inch reduced shank makes it compatible with standard drill press chucks and heavy-duty hand drills without requiring a Jacobs-style chuck upgrade. It is a practical choice for low-to-mid volume production runs and field service work requiring oversized holes.

Installation Notes

Installation should be performed by a qualified machinist or technician familiar with drill press operation and cutting tool safety. Secure the reduced shank firmly in the chuck and verify there is no runout before beginning a cut. Use appropriate cutting fluid when drilling ferrous metals to extend tool life and reduce heat buildup. Always wear appropriate eye protection and secure the workpiece before drilling.
