KnKut 13-pc Left Hand Jobber Length Drill Bit Set 1/16″-1/4″ (13KK6)

Description

The KnKut 13-pc Left Hand Jobber Length Drill Bit Set 1/16″-1/4″ (13KK6) is a specialized tool designed for precision and effectiveness in challenging drilling applications. Manufactured in the USA from premium grade Molybdenum High Speed Steel (HSS) with high vanadium content, these drill bits are built to perform. Each bit undergoes a unique salt nitride treatment, which penetrates the tool’s surface, significantly enhancing its hardness and allowing it to drill through tough materials like stainless steel and titanium alloy with ease. The 135-degree split point tip is a standout feature, as it eliminates the need for a center punch or pilot hole, allowing for faster and more accurate drilling. This set is particularly valuable for its left-hand rotation, making it an ideal choice for the common problem of removing broken studs. When operated in reverse, these bits can often loosen a broken stud while drilling, potentially eliminating the need for a separate screw extractor and saving valuable time and effort.

KEY FEATURES AND BENEFITS:

• Optimized for Broken Stud Removal: Left-hand rotation is specifically designed to help loosen broken studs or fasteners while drilling, often preventing the need for additional extraction tools.
• Superior Material & Treatment: Made from high-grade Molybdenum High Speed Steel with high vanadium content and salt nitride treated, ensuring exceptional hardness and extended tool life when drilling tough materials.
• Precision Drilling: The 135-degree split point tip allows for immediate drilling without the need for a center punch or pilot hole, producing rounder and more accurate holes efficiently.
• Versatile Material Compatibility: Engineered to drill through demanding materials such as stainless steel and titanium alloy, providing reliable performance where standard bits may fail.
• Cost-Effective Performance: Designed to offer the lowest cost per hole, reflecting their efficiency, durability, and reduced need for replacement.
• Proudly Made in USA: Manufactured in the United States, ensuring high-quality standards and consistent performance.

SPECIFICATIONS:

• Drill Bit Sizes: 1/16″, 5/64″, 3/32″, 7/64″, 1/8″, 9/64″, 5/32″, 11/64″, 3/16″, 13/64″, 7/32″, 15/64″, 1/4″
• Material: Molybdenum High Speed Steel (HSS) with high vanadium content
• Tip Angle: 135-degree split point
• Treatment: Salt nitride treated
• Orientation: Left Hand Rotation
• Length Type: Jobber Length
• Included: 13 drill bits and a metal index case

HOW TO USE:

1. Select the Correct Bit: Choose the appropriate size left-hand drill bit for the broken stud or the hole you need to drill. For broken studs, select a bit slightly smaller than the stud’s diameter.
2. Prepare Your Drill: Insert the selected left-hand drill bit securely into your drill chuck.
3. Set Drill to Reverse: Crucially, ensure your drill motor is set to reverse mode (counter-clockwise rotation). This is essential for the left-hand bits to function correctly and potentially loosen a broken stud.
4. Position the Bit: For broken studs, carefully position the drill bit in the center of the broken fastener. For general drilling, place the tip where you intend to create the hole. The 135-degree split point tip should prevent walking.
5. Begin Drilling: Apply steady, even pressure and begin drilling. Allow the bit to do the work; do not force it.
6. Monitor for Stud Removal (if applicable): While drilling a broken stud, observe if the stud begins to turn and loosen. If it does, continue drilling until it completely backs out.
7. Clear Debris: Periodically clear chips and debris from the hole to prevent clogging and overheating.
8. Complete the Hole: Continue drilling until the desired depth is achieved or the broken stud is removed.
9. Clean and Store: After use, clean the drill bit and return it to its metal index case for proper storage.
