KnKut 5pc Left Hand Step Point Mechanics Drill Bit Set (5KK10-LH)

The KnKut 5pc Left Hand Step Point Mechanics Drill Bit Set (5KK10-LH) is a specialized tool engineered for the efficient removal of broken studs and fasteners. This high-quality set is designed with a unique left-hand rotation, allowing the drill bit to spin counter-clockwise. When used in a drill motor set to reverse mode, this action can often loosen the broken stud as the hole is being drilled, potentially eliminating the need for a separate screw extractor. This feature significantly streamlines repair processes, saving valuable time and effort.

KEY FEATURES AND BENEFITS:

• Left-Hand Rotation: Specifically designed to rotate counter-clockwise, which can loosen broken studs as you drill, often making screw extractors unnecessary.
• Step Point Design: Helps create accurate, round holes and can minimize the need for pre-drilling or center punching for efficient starts.
• Mechanics Length: Shorter overall length and flute provide increased rigidity, reducing deflection and breakage, ideal for tight spaces or demanding applications.
• High-Performance Material: Constructed from Hi-Molybdenum high-speed steel with high vanadium content for extended tool life and resistance to wear.
• Salt Nitride Treated: Surface treatment enhances hardness and durability, allowing for effective drilling in tough materials like stainless steel and titanium alloys.
• Made in USA: Manufactured in the United States, indicating a focus on quality craftsmanship and reliable performance.
• Cost-Effective Solution: Provides a durable and efficient method for broken stud removal, potentially reducing overall repair costs.

HOW TO USE:

1. Preparation: Ensure the work area is clear and stable. Wear appropriate personal protective equipment, including safety glasses.
2. Tool Selection: Select the appropriate size KnKut left-hand drill bit that is slightly smaller than the broken stud you intend to remove.
3. Drill Setup: Securely chuck the chosen drill bit into your drill motor. Crucially, set your drill motor to its reverse (counter-clockwise) rotation mode.
4. Positioning: Carefully center the drill bit on the broken stud.
5. Drilling: Apply steady, consistent pressure and begin drilling slowly. As the left-hand drill bit cuts into the broken stud, its reverse rotation may cause the stud to loosen and unthread itself.
6. Extraction: If the stud begins to turn, continue drilling until it completely unthreads from the hole. If it doesn't unthread, proceed with a standard extraction method (e.g., using a screw extractor in the drilled hole, if necessary).
7. Cleanup: Once the stud is removed, clean any debris from the area.

BENEFITS OF USING KNKUT 5PC LEFT HAND STEP POINT MECHANICS DRILL BIT SET (5KK10-LH):

• Effortless Stud Removal: Simplifies the often challenging task of extracting broken studs, significantly reducing frustration and effort.
• Time Savings: The potential to unthread broken fasteners while drilling minimizes the need for extra steps or specialized tools, speeding up repairs.
• Versatile Application: Effectively drills through and helps remove fasteners from a wide range of materials, including notoriously tough metals.
• Reduced Tool Breakage: The mechanics length design and durable construction lead to a more rigid bit, lessening the chances of snapping during use.
• Precise Hole Creation: The step-point tip ensures accurate starts and clean holes, which is essential for subsequent operations or replacement fasteners.
• Enhanced Tool Life: Superior materials and treatment ensure these bits maintain their cutting edge longer, providing consistent performance over many uses.
