Description
The KnKut 29-pc Jobber Drill Bit Set w/ 3/8" Reduced Shanks (29KK38DB) is engineered for precise and efficient drilling in demanding materials. This comprehensive set includes fractional sizes from 1/16" through 1/2" in 1/64" increments, providing a bit for nearly any task. Each bit is manufactured in the USA from premium-grade Molybdenum high-speed steel, featuring a high vanadium content for enhanced material properties. The drill bits undergo a specialized salt nitride treatment, which hardens the tool's surface, enabling them to maintain performance when drilling through challenging substances like stainless steel and titanium alloy. The 135-degree split point tip on each bit is a key design element, allowing for immediate penetration without the need for a center punch or pilot hole, and contributing to the creation of rounder, more accurate holes with minimal effort. This set is a valuable addition for professionals and serious DIYers seeking tools that perform consistently in tough applications.
KEY FEATURES AND BENEFITS:
- Comprehensive Sizing: Includes 29 fractional drill bits ranging from 1/16" to 1/2" in 1/64" increments, providing a wide array of options for various drilling needs.
- Enhanced Material Strength: Made from premium Molybdenum high-speed steel with high vanadium content and salt nitride treated, ensuring high hardness and resilience for extended tool life.
- Reduced Shank Design: Features 3/8" reduced shanks on sizes 25/64" and above, allowing larger drill bits to fit into standard 3/8" drill chucks for broader compatibility.
- Precise Drilling: The 135° split point tip prevents drill bit "walking" and facilitates quick material penetration, resulting in rounder, more accurate holes without prior preparation.
- Versatile Material Application: Specifically designed to drill tough materials such as stainless steel, titanium alloy, and hard steels, making it suitable for demanding jobs.
- Cost-Effective Performance: Engineered for high efficiency and longevity, contributing to a lower cost per drilled hole over the lifespan of the bits.
SPECIFICATIONS:
- Set Size: 29 pieces
- Bit Sizes: 1/16" through 1/2" by 64ths
- Shank Type: 3/8" Reduced Shanks on Sizes 25/64" and Above
- Material: Premium Grade Molybdenum High Speed Steel (HSS) with High Vanadium Content
- Treatment: Salt Nitride Treated
- Tip Angle: 135 Degree Split Point Tip
- Manufacturing Origin: Made In USA
- Included: 29 KnKut Jobber Length Drill Bits, organized in a metal index case or similar storage solution (standard for this type of set).
HOW TO USE:
- Select the Correct Bit: Choose the appropriate drill bit size from the set based on your specific hole diameter requirement.
- Secure the Bit: Insert the drill bit firmly into your drill's chuck, ensuring the shank is seated correctly and tightened to prevent slippage during operation.
- Prepare the Material: Position the material securely. For most applications with these bits, a center punch or pilot hole is not required due to the 135° split point.
- Initiate Drilling: Place the tip of the drill bit precisely where you want the hole. Apply steady, moderate pressure and begin drilling at an appropriate speed for the material.
- Maintain Speed and Pressure: Continue drilling, maintaining consistent pressure and allowing the bit to cut through the material. For hard materials, a slower speed and appropriate cutting fluid may be beneficial to extend bit life.
- Clear Chips: Periodically withdraw the bit slightly to clear chips from the hole, especially when drilling deep holes, to prevent clogging and overheating.
- Complete the Hole: Continue until the hole is drilled through the material. Once complete, relieve pressure and carefully withdraw the drill bit from the hole.
