SUPERIOR SPEED AND DURABILITY FOR GENERAL PURPOSE DRILLING
Upgrade your drilling efficiency with the Bosch BL2171 11/16 Inch Black Oxide Drill Bit. Engineered for professionals who require reliability across a wide range of materials, this bit features a premium black oxide coating that provides superior durability and heat resistance, lasting up to 50% longer than standard high-speed steel bits. The advanced "Speed Helix" design aggressively removes chips and debris, allowing for drilling speeds up to three times faster than conventional options. Whether you are working with mild steel, copper, brass, aluminum, or hardwoods like oak and maple, this bit delivers consistent, clean performance.
Designed for versatility and ease of use, the BL2171 features a 1/2-inch reduced shank (commonly known as Silver and Deming), enabling this large-diameter cutter to fit securely into standard 1/2-inch drill chucks. The precision-manufactured 135-degree split point tip starts on contact, eliminating the need for a center punch and preventing the frustrating "walking" or skating often experienced with standard bits. From heavy-duty metal fabrication to complex woodworking and plastic applications, this tool is built to handle the heat and keep on drilling.
Key Features
- Speed Helix Design: Aggressive flute geometry allows for three times faster drilling than standard bits.
- Black Oxide Coating: Resists heat buildup and extends bit life by 50% compared to standard high-speed steel.
- Reduced Shank: 1/2-inch reduced shank ensures compatibility with standard 1/2-inch drill driver chucks.
- No-Skate Split Point: Starts immediately on contact without walking, ensuring accurate hole placement.
- Multi-Material Versatility: Excellent for drilling steel, copper, aluminum, brass, wood, PVC, and composite materials.
- Heat Management: Engineered to reduce friction and heat generation for easier drilling.

Pro-Tip: When drilling large holes with bits like this 11/16-inch cutter, heat is the enemy. To extend the life of the bit, reduce your drill's RPM speed and apply firm, steady pressure. If drilling into metal, always use a cutting fluid or lubricant to keep the cutting edge cool and sharp.
