KnKut reduced shank drill bit details
KnKut 7/8" Fractional SP 1/2" Reduced Shank Drill Bit (KK12SP-7/8)
The KnKut 7/8" Fractional SP 1/2" Reduced Shank Drill Bit (KK12SP-7/8) is an advanced cutting tool engineered for precision and durability. Designed and manufactured in the USA, this drill bit combines innovative features to deliver exceptional performance across a variety of challenging materials. Its unique step point design allows for accurate starts without the need for a center punch, significantly reducing bit walking and ensuring clean, precise holes from the first contact.
KEY FEATURES AND BENEFITS:
Accurate Hole Starting: Features a split tip point that enables precise drilling without a center punch, preventing the bit from "walking" on the workpiece surface.
Extended Tool Life: The step drill design significantly reduces heat generation during drilling, which helps to preserve the cutting edge and prolong the lifespan of the drill bit.
Enlarges Existing Holes Safely: Specifically designed to enlarge previously drilled holes without causing damage to the drill bit's tip.
Secure Chuck Grip: Equipped with 3-flats on the shank to prevent slippage in the drill chuck, ensuring stable and reliable operation.
Versatile Material Application: Performs effectively on a wide range of materials including hard steel, brass, sheet metal, and acrylics, making it a versatile addition to any toolkit.
USA Made Quality: Manufactured in the United States, ensuring high standards of quality control and material integrity from raw materials to the finished product.

Prepare Your Workpiece: Securely clamp the material you intend to drill to a stable surface to prevent movement during operation.
Select Your Drill: Insert the 1/2" reduced shank of the KnKut KK12SP-7/8 drill bit into your drill chuck. Tighten the chuck firmly around the three flats on the shank to ensure it's securely held and won't slip.
Set Drill Speed: Choose an appropriate drill speed based on the material you are drilling. Slower speeds are generally recommended for harder materials to reduce heat and maintain control.
Initiate Drilling: Position the drill bit directly over the desired drilling location. Apply steady, moderate pressure as you begin drilling. The split tip point will help the bit start accurately without needing a pilot hole or center punch.
Maintain Pressure and Lubrication: Continue to apply consistent pressure. For optimal performance and to further reduce heat and friction, especially when drilling hard materials, apply a suitable cutting fluid or lubricant as you drill.
Clear Chips: Periodically withdraw the drill bit slightly from the hole to clear chips, particularly when drilling deep holes. This prevents chip buildup, reduces heat, and improves cutting efficiency.
Complete Hole: Continue drilling until the desired hole depth or through-hole is achieved. Once finished, slowly withdraw the drill bit from the workpiece.
