Description
Product Overview
The 135 Degree Heavy Duty Mechanics Length Drill Bit by Cle Line is engineered for demanding applications where precision, strength, and longevity are essential. Constructed from high‑speed steel (HSS), the tip maintains sharpness even after repeated use on hardened metals, while the RHS/RHC shank ensures a secure, wobble‑free connection to a wide range of power drills. Measuring 5/64 inch in diameter, this bit offers a perfect balance between rigidity and flexibility, allowing users to tackle both fine detail work and larger bore requirements. The 135° twist geometry reduces torque resistance, delivering smoother entry and less material strain, which translates into cleaner holes and reduced wear on both the bit and the machine. Weighing just one pound, the bit is lightweight enough for extended use without fatigue, yet robust enough to withstand the rigors of professional workshops. Made in the United States, each unit undergoes strict quality control to guarantee consistent performance across every batch.

Usage
This drill bit excels in a variety of environments, from automotive repair bays and industrial fabrication shops to home workshops and hobbyist projects. Its 135° geometry makes it ideal for drilling through steel, aluminum, brass, and other alloys commonly encountered in mechanical work. At the same time, the HSS tip provides excellent performance on hardwoods, softwoods, and composite materials, making it a versatile tool for electricians, carpenters, and DIY enthusiasts alike. Whether you are installing fasteners, creating pilot holes for bolts, or fabricating custom brackets, the bit’s length offers superior reach into confined spaces where standard bits cannot access. The RHS/RHC shank design is compatible with most modern drill chucks, ensuring a tight fit that minimizes slippage during high‑torque operations. For users who demand accuracy, the bit’s precise tolerances help maintain hole alignment, reducing the need for re‑drilling and saving valuable time on the job.
