Product Details
Heavy-Duty HSS Reduced Shank Drill Bits (Silver & Deming)
Expand Your Drilling Capacity with Standard Chucks
Xiaoman Tools' Reduced Shank Drill Bits (also known as Silver & Deming drills) are the perfect solution for drilling large-diameter holes using standard 1/2-inch (13mm) drill chucks. Designed for heavy-duty applications, these bits expand the capability of your portable drills and drill presses without the need for specialized heavy machinery.
Key Features & Advantages
- Universal 1/2" Reduced Shank: The precisely machined 1/2-inch (12.7mm) or 13mm round shank fits perfectly into all standard drill chucks, offering secure gripping power and preventing slippage during heavy-torque applications.
- Premium Black Oxide Finish: The industrial black oxide surface treatment effectively retains cutting fluids, reduces friction, and provides excellent corrosion and rust resistance.
- Industrial Grade HSS Material: Available in HSS 4241 for economical general-purpose use, or HSS M2 (6542) for prolonged life and increased wear resistance on harder metals.
- Precision Cutting Edge: Engineered with a 135-degree split point (or 118-degree standard point upon request) to ensure quick penetration and reduce "walking" on the workpiece.
