KnKut 8-Piece Step Point 1/2" Reduced Shank Drill Bit (8KK12SP)

The KnKut 8-Piece Step Point 1/2" Reduced Shank Drill Bit Set (8KK12SP) offers a high-performance solution for demanding drilling tasks. Manufactured in the USA, this set is engineered to provide precise and efficient drilling in a variety of challenging materials. Each bit combines the benefits of a split tip point with a step drill design, ensuring accurate starts without needing a center punch and significantly reducing heat buildup during operation. This unique design not only extends the life of the drill bit but also improves drilling efficiency, making it an ideal choice for professionals and serious DIYers.

KEY FEATURES AND BENEFITS:

• Accurate Hole Starting: The step point design allows for precise hole initiation without pre-drilling or using a center punch, saving time and improving accuracy.
• Reduced Heat Generation: The unique geometry of the step point minimizes friction and heat during drilling, preserving the bit's sharpness and extending its overall lifespan.
• Versatile Material Compatibility: Effectively drills through hard steel, brass, sheet metal, and acrylics, making it suitable for a wide range of applications.
• Enlarge Existing Holes: Designed to enlarge pre-drilled holes cleanly and efficiently without damaging the bit's tip or compromising hole quality.
• Enhanced Chuck Grip: The 1/2" reduced shanks on all bits, featuring three flats for sizes 3/16" and above, prevent slippage in standard 1/2" drill chucks.
• USA Made Quality: Manufactured in the United States from high-grade Molybdenum High Speed Steel with high Vanadium content, ensuring consistent quality and superior performance.
• Improved Tool Life: Salt nitride treatment penetrates the tool's surface, increasing hardness and providing exceptional wear resistance.

SPECIFICATIONS:

• Included in Set:
• One 9/16" Drill Bit
• One 5/8" Drill Bit
• One 11/16" Drill Bit
• One 3/4" Drill Bit
• One 13/16" Drill Bit
• One 7/8" Drill Bit
• One 15/16" Drill Bit
• One 1" Drill Bit
• Plastic storage case

HOW TO USE:

1. Select the Correct Bit: Choose the drill bit size that matches the desired hole diameter from the set (9/16" to 1").
2. Secure the Bit: Insert the 1/2" reduced shank of the chosen drill bit firmly into your drill's 1/2" chuck. Ensure the three flats on the shank (for sizes 3/16" and above) are properly engaged for maximum grip and to prevent slippage. Tighten the chuck securely.
3. Prepare the Material: Mark the center of your drilling location. For larger holes or harder materials, consider clamping the workpiece to prevent movement during drilling.
4. Begin Drilling: Position the drill bit's step point directly on the marked spot. Apply steady, moderate pressure and start the drill at a consistent speed appropriate for the material you are drilling. The step point will self-center and begin cutting without wandering.
5. Maintain Pressure and Speed: Continue drilling, maintaining consistent pressure. The step design will help clear chips and reduce heat. Avoid excessive force, which can dull the bit or cause breakage.
6. Clear Debris: Periodically lift the drill bit slightly to allow chips to clear from the hole, especially when drilling deep holes or in soft materials.
7. Finish Drilling: Continue until the desired depth is reached or the bit passes through the material. Slowly withdraw the drill bit while it is still spinning to clear any remaining debris.
8. Clean and Store: After use, clean the drill bits of any residue and return them to the provided plastic storage case to protect them and keep the set organized.
