KnKut 15/16" Fractional SP 1/2" Reduced Shank Drill Bit (KK12SP-15/16)

The KnKut 15/16" Fractional SP 1/2" Reduced Shank Drill Bit (KK12SP-15/16) is a high-performance, USA-made tool engineered for precision drilling in a variety of challenging materials. This drill bit stands out with its innovative design, combining a step point with a split tip, which allows for accurate hole starting without the need for a center punch. Crafted from Hi-Molybdenum tool steel, it's built to withstand higher drilling temperatures, maintaining its sharpness and integrity even when working with demanding materials like work-hardened stainless steel and titanium alloys. Its 1/2" reduced shank ensures compatibility with a wider range of drill chucks, making it a versatile addition to any toolkit.

KEY FEATURES AND BENEFITS:

• Self-Centering Precision: The unique Step Point with a 135° Split Tip allows for immediate, accurate hole starts, eliminating bit walking and removing the need for pre-drilling or a center punch.
• Extended Tool Life: The distinctive step drill design actively reduces heat buildup during operation, significantly prolonging the cutting edge's sharpness and the overall lifespan of the drill bit.
• Versatile Hole Creation: Not only is it perfect for starting new holes, but its design also allows for cleanly enlarging existing holes without causing damage to the drill bit's point or the workpiece.
• Enhanced Grip Security: Featuring a 1/2" reduced shank with three flats, this drill bit provides a secure hold in your drill chuck, preventing slippage even during high-torque applications.
• High-Performance Material: Made from Hi-Molybdenum tool steel with a space-age Nitro-Carbonized treatment, it’s optimized for drilling through difficult materials, including hard steel, brass, sheet metal, and especially work-hardened grades of stainless steel and titanium.

SPECIFICATIONS:

• Drill Bit Diameter: 15/16 inches
• Shank Diameter: 1/2 inch
• Shank Type: Reduced with 3 flats
• Point Angle: 135 degrees
• Point Type: Step Point with Split Tip
• Material: Hi-Molybdenum Tool Steel (HSS) with Nitro-Carbonized treatment
• Length Type: Jobber Length
• Included in Purchase: One KnKut 15/16" Fractional SP 1/2" Reduced Shank Drill Bit (KK12SP-15/16)

HOW TO USE:

1. Secure the Workpiece: Always ensure the material you are drilling is firmly clamped or secured to prevent movement during the drilling process.
2. Insert the Bit: Loosen your drill chuck and insert the 1/2" reduced shank of the KnKut KK12SP-15/16 drill bit into the chuck. Tighten the chuck firmly around the three flats on the shank to prevent slippage.
3. Select Appropriate Speed: For harder materials like stainless steel, use a slower drill speed. For softer materials like acrylic or brass, a moderate to higher speed may be suitable. Consult your drill's manual or a drilling chart for optimal RPMs based on material and drill bit size.
4. Apply Steady Pressure: Position the drill bit directly over your desired drilling location. The self-centering step point will prevent the bit from walking. Apply steady, consistent pressure to begin drilling. Avoid excessive force, as the bit's design is optimized for efficient material removal.
5. Maintain Cooling (Optional but Recommended): For extended drilling in very hard materials, consider using a cutting fluid or lubricant to further reduce heat and extend tool life.
6. Clear Chips: Allow the flutes to clear chips efficiently. If drilling deep holes, occasionally withdraw the bit slightly to clear accumulated chips.
7. Complete the Hole: Continue drilling with steady pressure until the desired depth is reached or the hole is complete.
8. Clean Up: Once drilling is finished, safely remove the bit from the chuck and clean any debris from the workpiece and drill bit.
