KnKut 29pc Jobber Drill Bit Set 1/16″-1/2″ 64th w/3/8″ Shanks (29KK38)

Description

The KnKut 29pc Jobber Drill Bit Set 1/16″-1/2″ 64th w/3/8″ Shanks (29KK38) is an essential collection for anyone performing precision drilling in various materials, including demanding metals. Manufactured in the USA, this set offers a comprehensive range of drill bit sizes, from 1/16″ up to 1/2″ by 64ths. Each bit is crafted from a high-grade Molybdenum high-speed steel with high vanadium content, providing excellent durability and performance.

KEY FEATURES AND BENEFITS:

• 29-Piece Fractional Set: Offers a complete range of sizes from 1/16″ through 1/2″ by 64ths, providing the right bit for diverse applications.
• 3/8″ Reduced Shanks: Bits 25/64″ and larger feature reduced shanks, allowing them to fit into standard 3/8″ drill chucks, increasing versatility.
• High-Grade Molybdenum High-Speed Steel: Manufactured from premium HSS with high vanadium content, ensuring superior strength, heat resistance, and extended tool life.
• Salt Nitride Treated: A specialized surface treatment penetrates the steel, significantly increasing hardness for efficient drilling in challenging materials like stainless steel and titanium alloy.
• 135° Split Point Tip: This advanced tip design allows for self-centering, eliminating the need for a center punch or pilot hole and reducing bit “walking” for more accurate starts.
• Produces Rounder, More Accurate Holes: The precise design and manufacturing contribute to consistently producing high-quality, clean holes.
• Lower Cost Per Hole: Due to their exceptional durability and efficiency, these bits offer a long service life, reducing overall drilling expenses.
• Made in USA: Manufactured in the United States, ensuring high quality control standards and reliable performance.

HOW TO USE:

1. Select the Correct Bit Size: Identify the specific drill bit size (from 1/16″ to 1/2″ by 64ths) that matches the hole you intend to drill.
2. Secure the Bit in the Drill Chuck: Insert the shank of the selected drill bit into your drill’s chuck. For bits 3/16″ and larger, align the three flats on the shank with the chuck jaws for a secure grip. Tighten the chuck firmly to prevent slippage during operation.
3. Prepare the Workpiece: Ensure your material is securely clamped or held to prevent movement during drilling. For optimal results, especially with tougher materials, apply a suitable cutting fluid or lubricant to the drilling area.
4. Position the Drill: Place the 135° split point tip of the drill bit precisely where you want to make the hole. The self-centering design helps prevent the bit from wandering.
5. Begin Drilling: Apply consistent, steady pressure. Start the drill at a lower speed, gradually increasing it as the bit engages the material. Avoid excessive pressure, as this can generate heat and reduce bit life.
6. Maintain Consistent Pressure and Speed: Allow the bit to do the work. The salt nitride treatment and HSS material enable efficient cutting through tough materials like stainless steel and titanium.
7. Clear Chips and Cool Down: Periodically withdraw the bit slightly to clear chips from the hole, especially when drilling deep holes. Continue applying cutting fluid as needed to dissipate heat and lubricate the cutting edge.
8. Complete the Hole: Continue drilling until the desired depth is reached or the bit passes completely through the material.
9. Clean and Store: Once finished, clean any debris from the drill bit and return it to its designated slot in the metal index case for protection and organization.
