KnKut 1" Fractional Step Point 1/2" Reduced Shank Drill Bit (KK12SP-1)

The KnKut 1" Fractional Step Point 1/2" Reduced Shank Drill Bit (KK12SP-1) is a precision-engineered cutting tool designed to provide exceptional accuracy and performance in a wide array of demanding drilling applications. This specialized drill bit offers a unique combination of features that ensure clean, efficient holes in even the toughest materials.

KEY FEATURES AND BENEFITS:

• Accurate, Self-Centering Starts: The innovative split tip and step drill design allow the bit to start precisely without a center punch, preventing "walking" on the material surface.
• Reduced Heat Buildup: Engineered to minimize friction and heat generated during drilling, which significantly extends the lifespan of the drill bit and maintains its cutting edge.
• Enlarges Existing Holes Effectively: Designed to smoothly enlarge pre-drilled holes without damaging the bit's point, offering versatility for various tasks.
• Superior Material Composition: Manufactured from Hi-Molybdenum tool steel with high Vanadium content, and salt nitride treated for enhanced surface hardness and improved wear resistance.
• Secure Shank Design: Features a 1/2" reduced shank with three flats for sizes 3/16" and above, ensuring a strong, non-slip grip in the drill chuck.
• Versatile Material Application: Performs exceptionally well across a broad spectrum of materials, including hard steel, brass, sheet metal, acrylics, work-hardened stainless steel, and titanium alloys.

SPECIFICATIONS:

• Diameter: 1 inch
• Shank Size: 1/2 inch reduced shank
• Shank Type: 3 flats on shank
• Point Type: Split tip point with step drill design
• Material: Hi-Molybdenum tool steel with high Vanadium content, salt nitride treated
• Length: Jobber length
• Included in Purchase: One KnKut 1" Fractional Step Point 1/2" Reduced Shank Drill Bit (KK12SP-1)

HOW TO USE:

1. Preparation: Always wear appropriate safety glasses and gloves before starting any drilling operation. Ensure your workpiece is securely clamped to prevent movement during drilling.
2. Select Correct Speed: For optimal performance and tool life, select the appropriate drill speed for the material you are working with. Generally, harder materials require slower speeds.
3. Insert and Secure Bit: Insert the 1/2" reduced shank of the KnKut KK12SP-1 drill bit firmly into your drill chuck. Tighten the chuck securely to ensure the three flats on the shank are gripped properly, preventing slippage.
4. Positioning: Place the tip of the drill bit precisely where you intend to drill. Due to its self-centering step point, a center punch is not typically required.
5. Start Drilling: Begin drilling by applying steady, consistent pressure. Allow the bit to cut rather than forcing it through the material. The split tip will help initiate the cut accurately.
6. Maintain Pressure and Lubrication (if needed): Continue drilling with even pressure. For very hard materials or deep holes, consider using a cutting fluid or lubricant to reduce friction and heat, which will further extend the life of the drill bit.
7. Clear Chips: Periodically back the drill bit out of the hole to clear chips, especially when drilling deeper holes. This prevents chip buildup and reduces heat.
8. Completion: Once the hole is drilled, retract the bit completely and safely. Unclamp your workpiece and clean any debris.
