TCT Annular Cutter Set 5/8" to 1-1/16" Cutting Diameter Compatible with Mag Drill Bits Kit CNC Machined Cutters (35MM)

Parameter Details:Drilling Diameter Range: 5/8", 3/4", 7/8", 15/16", 1", 1-1/16"Cutting Depth: 35mmTool Head Material: TCT Carbide (Tungsten Carbide Tipped)Handle Diameter Specification: 10mm (Universal Handle)Recommended Speed Range: 62-1592 RPM (depending on diameter and material)Central Guide Pin: φ6mm spring pin (standard configuration)Packaging Method: Plastic BoxTCT Drill Bit for Metal Drilling – Tungsten Carbide Tip, High Precision, Universal 10mm ShankDiscover the ultimate drilling performance with our TCT (Tungsten Carbide Tip) drill bits, designed for superior durability and precision when working with hard materials like stainless steel, carbon steel, and aluminum. With a tungsten carbide cutting head (HRA ≥ 90), these bits offer outstanding wear resistance and maintain sharpness for longer periods, significantly outperforming traditional HSS drill bits.The multi-tooth cutting edge design effectively distributes force, reducing vibration and runout, while precision grinding enhances the sharpness and accuracy of each cut. The double-helix chip removal groove ensures fast evacuation of metal chips, preventing clogging, overheating, and reducing the risk of tool damage. This makes it ideal for continuous, high-speed drilling.Widely used in various fields such as power equipment installation, sheet metal fabrication, air conditioning pipeline installation, steel structure construction, automotive manufacturing, and mechanical equipment installation, this tool is an ideal choice for professionals like electricians, sheet metal workers, and assembly technicians.

• High-Performance Tungsten Carbide Tip (HRA ≥ 90): Annular cutter set Designed with a tungsten steel alloy cutting head (HRA ≥ 90), this drill bit offers exceptional wear and heat resistance, delivering long-lasting sharpness even on hard metals like stainless steel and carbon steel,The durability is significantly longer than traditional HSS drill bits, offering a lower overall cost of use.
• Drilling diameter range: The annular cutter set includes six drill bits 5/8", 3/4", 7/8", 15/16", 1", 1-1/16"(16mm, 19mm, 22mm, 24mm, 25mm, 27mm). Cutting Depth: 1-3/8" (35mm).The multi-tooth design ensures smooth and efficient drilling, reducing vibration and cutting resistance. Precision-ground edges result in accurate hole diameters and cleaner hole edges, improving overall drilling precision.
• Efficient Double-Helix Chip Removal: The TCT annular cutter set double-helix groove quickly evacuates drill chips, preventing clogging and overheating. This design ensures a stable drilling temperature and produces smooth, burr-free holes for safer and more consistent operation.
• Universal 10mm Shank for Versatile Compatibility: The TCT annular cutter standard universal handle diameter is 10mm. The two grooves can fix the drill bit more stably. There is no need for an adapter. It can be directly adapted to common equipment such as electric drills, magnetic base drills, bench drills, drilling machines and lathes. Whether it is a workshop production line or outdoor engineering construction, it can handle them all with ease.
• Scientific rotational speed recommendation: The annular cutter precisely guide the operation based on the optimal tachometer of material and aperture. For instance, for 16-23mm, 1592-1107 RPM is recommended for aluminum materials, while 358-249 RPM is recommended for stainless steel. This helps you adjust the speed according to different materials, effectively reducing the risk of tool head wear and breakage
