MAKITA D-16841 HSS-Co Metal Drill Bit 12.5x151mm (5 pcs)

Metal Drill Bit  MAKITA  D-16841  HSS-Co Size 12.5x151mm. ( 5 pcs )
Features  
The D-16841 drill bit is in the HSS-Co (Cobalt) series, which is Makita's premium product line. This 12.5  mm drill bit is designed to handle thick, hard metal drilling with high heat generation.HSS-Co (High-Speed Steel with Cobalt): Approximately 5% cobalt (Co5) alloyed into high-speed steel enhances hot hardness, allowing the bit to effectively withstand high temperatures generated during drilling in stainless steel or hard metals.Fully Ground: Manufactured through full-length precision grinding (Fully Ground), resulting in sharp cutting edges, high dimensional accuracy, and uniform geometry, which is essential for drilling large holes in tough metals.135° Split Point: The 135-degree split point is the standard for large and hard metal drill bits, enabling the bit to bite into the workpiece instantly without the need for a center punch (Self-centering) and reducing the required feed pressure.                                                      Application
The MAKITA D-16841 HSS-Co drill bit is suitable for drilling difficult materials in industrial, mechanical, and maintenance applications requiring work on:Hard metals:Stainless steel (Inox)Acid-resistant and heat-resistant steelAlloyed and non-alloyed steel with high tensile strength (from $800 N/mm² and above)Cast ironGeneral trades: Large structural installation work, machinery assembly requiring 12.5  mm holes.Tools: Recommended for use with bench drills or high-power electric drills capable of clamping a 12.5  mm shank.
