Extra Length Drill Bits, Drill Bit Size (mm): 3.80 , Overall Length (mm): 87.0000 , Tool Material: Carbide , Coating/Finish: TiAlN , Coolant Through: Yes MPN:4143761

Extra Length Drill Bits are designed to meet the demands of professionals who require precision machining operations for applications such as aerospace, automotive manufacturing or engineering projects. Their carbide construction provides durability during tough jobs while the TiAlN coating offers lubricity and wear resistance ensuring longer drilling life. These bits are equipped with coolant through capability to dissipate heat, improve chip evacuation and reduce tool wear for accurate cutting performance. Typical users include metalworking shops, maintenance technicians or engineers who need extra reach when drilling into deep or confined areas where standard length bits may not reach or create access difficulties.
