Annular Cutter Carbide Tip Core Drill Bit 40CR Alloy

【Efficient Hole Cutting】 The annular cutter with a carbide tip and thin-walled hollow design helps remove less material than twist drills, allowing for clean cylindrical holes in steel plates and other metals.
【Precise Drilling】 The core drill features multiple cutting edges and a double alternating tooth geometry for more stable cutting, reduced clamping, and easier positioning during metalworking tasks.
【Material and Size】 Made of 40CR and hard alloy, this annular cutter has an overall length of approximately 95 mm and an opening depth of 50 mm for machining cylindrical holes in the workshop.
Wide Metal Application: Suitable for drilling open holes in ferrous and non-ferrous metals, including cast iron, stainless steel, aluminum, and copper, for maintenance and installation work. workshop.
【Pack and storage】 Includes 1 annular milling cutter and 1 storage box, convenient for transporting and organizing the drill bit between jobs when used with compatible magnetic drills and metal drilling setups.
