Annular Cutter Set Carbide TCT 13 pcs JESTUOUS

Tungsten carbide tipped weldon shank annular cutter, 11 pieces annular cutters and 2 pilot pins make up the CARBIDE ANNULAR CUTTER SET. Annular cutter, also known as slugger cutter or broach cutter, is a form of core drill used to create holes in metal. Unlike spiral drill bits and standard hole saws, annular cutters cut only a groove at the periphery of the hole, leaving a solid core or "slug" at the center. This design makes annular cutters a more efficient alternative.

There are two main types of annular cutters: high-speed steel (HSS) and tungsten carbide tipped (TCT). The biggest advantage of TCT annular cutters is their speed and ability to cut harder materials, particularly for boring larger diameter holes. This is because the teeth on TCT cutters are harder than HSS, allowing them to tackle more difficult materials. Additionally, the linear speed requirement for TCT cutters is higher than that of HSS.

The CARBIDE ANNULAR CUTTER SET includes the following specifications: - Cutting diameters: 1/2", 9/16", 5/8", 11/16", 3/4", 13/16", 7/8", 15/16", 1", 1-1/16", 1-1/8" - Cutting depth: 1-3/8" - Shank diameter: 3/4" - Shank style: weldon flat with 2 flats - Accessories: 2 pilot pins (6.34x90mm, 7.98x90mm) - Material: carbide tips + alloy steel - Type: core drill bit with weldon shank - Finish: white sand - Treatment: all-ground - Use: metal drilling - Packing: plastic box

The set's weldon shank design with 2 flats provides a more stable clamping for secure cutting and hole finishing. The shank diameter of 3/4 inch (19.05mm) is suitable for 120-degree, three-point bolt fastening for quick loading and unloading in the chuck bit clamp interface.

The cutter's layered cutting geometry design, ring cutting, and unique spiral groove enhance efficiency, reduce power consumption, and ensure smooth, easy, and quick chipping. For optimal performance, the recommended cutting speed is 20-25 m/min, with a feed rate of 0.08-0.13 mm/r and a feed rate of 36-60 mm/min.

When using the annular cutters, remember to insert the ejector pin inside, fill the coolant tank with oil lubrication, and take safety precautions to protect your eyes and fingers from the drilling cutter. The carbide tips with silver soldering are sharper than HSS annular cutters, and the weldon shank design allows for use on various magnetic drills, presses, mills, and large drill presses with tool holders.
