Nakkaa Annular Cutter Set 11 Pcs Shank Mag Drill Bits Cutting Depth, 2" Cutting Diameter 7/16" to 1-1/16" Inch Made with Super Tough M2AL High Speed Steel (HSS) Compatible with High Hardness Materials

Features

• 1）All Scenarios Compatible: The ring tool supports the mainstream brand magnetic drill, and can also be used with the milling machine and drilling machine to break through the single equipment limitation. The 3/4-inch double plane welding tool handle holds firmly and does not slip, whether it is in the metal workshop or outdoor construction site, it can be excellent to complete the drilling task.
• 2）Enhanced Performance Advanced Coating Technology: The aero-grade heat treatment process is adopted, and the cutting tool is made of M2AL HSS+ material, which has far better wear endurance than ordinary HSS drill bits. Special cutting edge design reduces friction coefficient, reduces thermal deformation, even continuous processing of stainless steel, cast iron, copper, alloy and other high hardness materials, still maintain sharp as new.
• 3）Meet The Requirements of Various Specifications: The package comes in 11 common sizes from 7/16" to 1-1/16" , 2 inch cutting depths to choose from, equipped with a 3/4 inch welded shank to easily handle sheet cutting, pipe opening, mold processing and other scenarios. Each drill bit is laser engraved size identification, with classification storage box, accurate access to tools within 10 seconds.
• 4）Burr-Less Process: Using CNC precision grinding multi-edge structure and polishing edge, drilling roughness Ra≤0.8μm, reduces the meed for reaming, with six cutting edges, clean and smooth cutting, improve cutting efficiency. Built-in automatic core guide needle, Minimal debris residue, especially suitable for precision instruments, aviation parts and other high-end processing fields.
• 5）Industrial-Grade Quality: Full metal reinforced shank impact endurance test more than 5000 times without deformation, precise cutting with high-precision blades, fast drilling, use lubricating oil, reduce friction, heat accumulation, extend downtime, improve bit longevity.
