Letter S 3-1/2" Flute Length 135&deg MPN:6001300

Letter S 3-1/2 flute length indexable carbide drill bit is specifically designed for drilling holes in a wide range of materials, including stainless steel, cast iron, aluminum, and titanium. It has a cylindrical shank that fits into power or hand held drills to bore accurate, square and clean holes. Its indexable cutting edge enhances its cutting efficiency, making it suitable for general metalworking applications like spot drilling, boring, countersinking, chamfering, and reaming. This type of drill bit comes in standard 1/4 x 20 thread which is common on many mills and lathes or can be custom made to accommodate your specific application requirement for length, flutes and point angle. The #135 spiral point allows a cleaner start with less skidding and chatter, reducing wear on the cutter and part. This drill bit is widely utilized by machine shops, metalworking businesses, automotive mechanics and aerospace industries to manufacture precise parts or conduct repairs requiring high quality hole creation or enlargement.
