Efficere Premium Drill Bit Set, 1/2 Reduced Shank, M2 HSS, 135-Degree Split Point, SAE Inch Size 9/16 - 1 by 1/16th

The EFFICERE 8-Piece Silver and Deming Drill Bit Set is your ideal choice for drilling large holes over half an inch in diameter on various materials, including wood, plastic, aluminum, copper, cast iron, mild steel, stainless steel, and sheet metals. This versatile set serves a wide range of applications, from woodworking and auto repairs to equipment and machinery maintenance, as well as metal fabrication.

Constructed from premium cobalt high-speed steel, these drill bits are built to last and deliver dependable strength. The 135-degree split point at the tip enables faster and more efficient drilling, as it facilitates self-centering and prevents the bits from walking or wobbling during the drilling process. The twist blade design with deep grooves effectively clears out chips and particles, further enhancing the drilling efficiency.

The superior golden titanium and black nitride dual coating applied to each drill bit holds lubricant better, resulting in a smoother drilling experience. This coating is also 80% more durable and corrosion-resistant than regular black enamel, making it suitable for heavy-duty applications. The 1/2-inch reduced shank of the drill bits is compatible with all drill presses and most power tools, while the unique tri-flatted shank end locks securely onto the 3-jaw chuck, eliminating any slippage during operation.
