The Walter 6.4 mm High-Speed Steel Jobber Drill Bit, 118, Point Angle, Bright Finish, 3-31/32" Overall Length, 2-31/64" Flute Length, Spiral Flute, Right Hand Cutting Direction is engineered for precision drilling in a variety of materials, including cast iron, steel, aluminum, brass, bronze, copper, graphite, plastic, synthetic materials, stainless steel, super-alloys, and titanium. This drill bit is designed to enhance operational efficiency and reduce downtime in industrial applications. Crafted from high-speed steel, the drill bit offers durability and resistance to wear, ensuring consistent performance over extended periods. The 118, point angle facilitates accurate centering and reduces the likelihood of wandering during drilling, which is crucial for maintaining hole quality and dimensional accuracy. The bright (uncoated) finish provides a smooth surface that minimizes friction and heat buildup, contributing to longer tool life and improved cutting performance. The spiral flute design effectively removes chips from the cutting area, reducing the risk of clogging and ensuring a cleaner hole. This feature is particularly beneficial when drilling through materials that tend to produce long, stringy chips. The right-hand cutting direction is standard for most drilling applications, making this bit versatile and compatible with a wide range of drilling equipment. With an overall length of 3-31/32" and a flute length of 2-31/64", this drill bit is suitable for applications requiring deeper drilling without compromising stability. The 6.4 mm diameter (0.2520" decimal equivalent) is ideal for tasks that demand precision and reliability. By incorporating this drill bit into your operations, you can achieve cleaner holes, reduce the need for rework, and enhance overall productivity.
