Extra Length Drill Bits, Drill Bit Size (mm): 4.40 , Overall Length (mm): 87.0000 , Tool Material: Carbide , Coating/Finish: TiAlN , Coolant Through: Yes MPN:4143772

Extra Long Drill Bits made of carbide provide durability, excellent wear resistance, and high heat tolerance in demanding jobs like heavy machinery or construction tasks offering up to a ten times longer life than steel bits. Equipped with TiAlN coating offers improved surface hardness & lubricity enabling easy cutting & reduced friction resulting in faster drilling times. Its coolant-through capability helps minimize heat generation maintaining optimal performance and reducing damage or breakage during use, which makes it essential for automotive, mining, military & heavy machinery applications where high precision or power is required on longer holes (87mm length). Hence Extra Length Drill Bits become a versatile must-have item among professionals handling heavy duty jobs requiring accuracy & longevity.
