MAKITA D-16782 HSS-Co Metal Drill Bit 9.50x125mm (5 pcs)

Metal drill bit  MAKITA  D-16782  HSS-Co size 9.50x125mm. ( 5 pcs )
Features The D-16782 drill bit is in the HSS-Co (Cobalt) series, which is a premium product line from Makita. This 9.50 mm drill bit is designed to handle drilling into thick, hard metals with high heat generation.HSS-Co (High-Speed Steel with Cobalt): Alloyed with approximately 5% Cobalt (Co5) in high-speed steel to enhance hot hardness properties, allowing the drill bit to withstand high temperatures generated during drilling of stainless steel or hard metals extremely wellFully Ground: Manufactured via full-length grinding (Fully Ground) to provide sharp cutting edges, high dimensional accuracy, and uniform geometry, aiding drilling efficiency and chip removal135° Split Point: 135-degree split point tip is the standard for hard metal drill bits, allowing the bit to penetrate the workpiece immediately without center punching (Self-centering) and helping reduce the required feed force                                                      Features
5% Cobalt (Co5): Extremely high heat resistance, allowing the cutting edge to retain excellent hardness when drilling stainless steel135° Split Point Tip: Helps start drilling precisely and reduces walking on hard surfacesFully Ground Quality: Superior cutting sharpness and uniform geometry allow smooth and fast drillingLonger service life than standard HSS: Ideal for heavy-duty applications and particularly hard materials                                                         
Application
MAKITA D-16782 HSS-Co drill bits are suitable for drilling difficult-to-machine materials in industrial, mechanical, and maintenance applications that require drilling into:Hard metals:Stainless Steel or InoxAcid-resistant and heat-resistant steelAlloy and non-alloy steel with high tensile strength (from 800  N/mm² and above)Cast IronGeneral mechanical work: Medium structural installation work, machinery assembly requiring 9.5  mm holesTools: Should be used with bench drill presses or high-power electric drills with a 10 mm or 13  mm chuck.
