PRESTO 10pcs Screw Extractor and Left Hand Drill Bit Set for Broken Bolt Removal

Product Description

EASY SCREW REMOVAL: Removing a broken screw from a damaged workpiece has never been easier! With the use of a left-hand drill bit alongside the screw extractor, the process is both convenient and efficient. The spiral grooves of the screw extractor reach deep into the screw, significantly enhancing grip strength. This makes it possible to effortlessly remove screws, studs, and bolts found around the house, in the garage, or on job sites.

HIGH-QUALITY COBALT HSS MATERIAL: Crafted from HSS M35 steel with a 5% cobalt composition, the PRESTO left-hand drill stands out compared to conventional high-speed steel options like 4241 or M2. M35 cobalt material is recognized for its hardened properties and exceptional cutting performance, leading to prolonged service life. It significantly improves wear resistance and effectively clears away chippings. Notably, Cobalt HSS is harder and more durable than other materials. Additionally, the construction utilizes high-strength chromium alloy steel, ensuring robustness and longevity.

INNOVATIVE DESIGN: The small size drills (5/64”, 7/64”) feature a unique 118° angle that minimizes axial resistance, facilitating seamless penetration into the workpiece. This design helps to prevent drill breakages often caused by drill walking. For larger drills (5/32”, 1/4”, 9/64”), the 135° angle with a split point ensures effective drilling even in heavy-duty applications involving tougher metals.

EFFICIENT ORGANIZATION AND STORAGE: To enhance convenience, this product comes packaged in a sturdy metal index case. This allows for easy portability and organization, making it straightforward to use whenever needed.

SET INCLUDES: The comprehensive set comprises 5 alloy steel screw extractors and 5 HSS Cobalt M35 left-hand drill bits. The screw extractors are identified by sizes #1, #2, #3, #4, and #5. The left-hand drill bits are available in sizes of 5/64", 7/64", 5/32", 1/4", and 19/64".

In summary, the PRESTO left-hand drill and screw extractor set is an essential tool for anyone dealing with screw removal challenges. Its reliable materials, thoughtful design, and practical storage solution make it an invaluable addition to any toolkit, ensuring users can tackle tough jobs with confidence and ease.
