KnKut 5-Piece Left Hand Jobber Length Drill Bit Set (5KK6)

Description

The KnKut 5-Piece Left Hand Jobber Length Drill Bit Set (5KK6) offers a specialized solution for a common problem: removing broken studs and screws. Unlike standard drill bits, these are meticulously designed to operate in reverse, leveraging their unique left-hand rotation to often loosen broken fasteners as you drill, frequently eliminating the need for separate screw extractors. Manufactured with pride in the USA, this set represents a commitment to quality and performance in demanding applications. Crafted from premium-grade Molybdenum high-speed steel with a high vanadium content, these drill bits undergo a salt nitride treatment that deeply penetrates the tool’s surface.

KEY FEATURES AND BENEFITS:

• Left Hand Rotation: Specifically designed to rotate in reverse, which helps to loosen and remove broken studs or screws while drilling, often eliminating the need for a separate screw extractor.
• Premium Material Composition: Made from high-grade Molybdenum high-speed steel with high vanadium content, providing superior strength and wear resistance.
• Salt Nitride Treated: The surface treatment enhances hardness, allowing the bits to effectively drill through tough materials like stainless steel and titanium alloy.
• 135-Degree Split Point Tip: Ensures precise starting without walking or skidding, eliminating the need for a center punch or pilot hole, and contributes to rounder, more accurate holes.
• Made in USA: Guarantees a high standard of manufacturing quality and reliability.
• Cost-Efficient Drilling: Designed for long life and efficient performance, aiming for a lower cost per hole and potentially drilling more holes than standard bits.

SPECIFICATIONS:

• What is included:
• 1 piece: 1/8″ Left Hand Jobber Length Drill Bit
• 1 piece: 5/32″ Left Hand Jobber Length Drill Bit
• 1 piece: 3/16″ Left Hand Jobber Length Drill Bit
• 1 piece: 7/32″ Left Hand Jobber Length Drill Bit
• 1 piece: 1/4″ Left Hand Jobber Length Drill Bit

HOW TO USE:

1. Select the Correct Bit: Choose a left-hand drill bit from the set that is smaller than the broken stud or screw you intend to remove.
2. Insert into Drill: Securely insert the chosen left-hand drill bit into your drill motor’s chuck.
3. Set Drill to Reverse: Crucially, ensure your drill motor is set to reverse mode. These bits are designed to operate in this direction.
4. Position and Drill: Carefully position the drill bit onto the center of the broken stud or screw. Apply steady, moderate pressure and begin drilling.
5. Observe and Remove: As the left-hand drill bit drills into the material, its reverse rotation may catch and loosen the broken fastener. If it begins to turn, continue drilling gently until the stud or screw is fully extracted. If it doesn’t loosen, you will create a pilot hole for further extraction methods if necessary.
