MAKITA D-16639 HSS-Co Metal Drill Bit 2.50x57mm (5 pcs)

Metal drill bit MAKITA D-16639 HSS-Co size 2.50x57mm.( 5 pcs )
Features MAKITA D-16639 HSS-Co metal drill bit, size 2.50 x 57 mm, is made from high-speed steel alloyed with 5% cobalt (HSS-Co) and precision fully ground. Features outstanding high heat resistance and edge retention. The 135° split point tip ensures precise starting without walking, making it ideal for drilling stainless steel and high tensile strength hard metals.   
Features                                                                                                                                                                        5% Cobalt (Co5): Extremely heat resistant, allowing the cutting edges to maintain excellent hardness when drilling stainless steel. 135° Split Point Tip: Ensures precise hole starting and reduces bit walking on hard surfaces. Fully Ground Quality: Superior cutting sharpness and uniform geometry for smooth, fast drilling. Longer Lifespan than standard HSS: Ideal for heavy-duty applications and exceptionally hard materials.                                                                                                       
Application                                                                                                                                                                        MAKITA D-16639 HSS-Co drill bit is suitable for drilling difficult-to-machine materials in industrial, mechanical, and maintenance applications that require drilling: Hard metals: Stainless steel (Inox), acid-resistant and heat-resistant steel, alloyed and non-alloyed steels with high tensile strength of 800 N/mm² and above, cast iron. General trades: Installation jobs requiring 2.5 mm holes in stainless steel materials. Other metals: Highly efficient for drilling aluminum, copper, and brass.
