Please choose a reasonable cutting speed.

• High-Speed Steel Material: Our mag drill bits are made of durable high-speed steel material, which undergoes low-temperature heating and precision grinding to achieve a hardness of 65 HRC. It has the superior properties of toughness, wear resistance, impact resistance, and long service life
• Efficient Cutting Design: This annular cutter set uses a geometric blade design to cut in layers, ensuring that each blade carries the appropriate load, reducing friction for efficient cutting. It can quickly and accurately drill holes up to 1" deep in steel, aluminum, copper, and other tough materials
• High Precision Annular Cutter: The HSS standard kit, processed with advanced CNC sharpening technology, has a small error and can drill precise burr-free holes without pre-drilling. It can cut steel quickly and accurately, and is ideal for creating large holes, overlapping holes, slotted holes, and edge-cutting
• 3/4" Weldon Shank: The slugger cutter comes with a 3/4" Weldon shank (2 flats) and fits most standard magnetic drills and machine tools such as milling machines with tool holders and large drill presses. The double-sided 90° crosscut clamp is designed for secure clamping and edge finishing, providing better fastening during operation
• Quick Chip Removal: The mag drill bits kit adopts an arc spiral chip groove design, which can effectively remove chips and waste, reduce the resistance of chip accumulation, and improve drilling efficiency. The large-capacity chip flute can prevent debris blockage and ensure smoother drilling
• Widely Used: Our HSS mag drill bits are compatible with most magnetic drills and machine tools and are used for cutting various materials such as structural steel, alloy steel, stainless steel, aluminum, brass, cast iron, etc. They are widely used in steel structure, bridge construction, shipbuilding, drilling platforms, railway construction, and machinery manufacturing
