KnKut 29-pc Jobber Drill Bit Set w/ 3/8" Reduced Shanks (29KK38DB)
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.
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).
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.
