A spade drill is a modular drill bit with replaceable tips, improved from indexable insert drills (U-drills). It is widely used in mechanical processing due to its advantages such as wide equipment compatibility and excellent deep-hole drilling capabilities. Below is a detailed introduction:
Drill Shank: Mostly made of high-strength heat-resistant alloy steel through heat treatment and precision machining, with two types of shanks: side-clamp shanks and Morse taper shanks. Side-clamp shanks are compatible with CNC lathes, machining centers, and other equipment; Morse taper shanks are used for traditional equipment such as upright drills and radial drills. The drill shank also has two chip evacuation forms (straight flute and spiral flute) and multiple specifications classified by length-to-diameter ratio (e.g., 3d, 5d, 7d), adapting to drilling requirements of different depths.
Insert: The mainstream materials are high-speed steel (usually M42 high-speed steel containing 8% cobalt) and cemented carbide. High-speed steel inserts have a diameter range of 9-68mm, while cemented carbide inserts range from 9-32mm (non-standard inserts can be customized to larger sizes). The insert adopts a symmetrical structure with double-edge cutting and central centering, positioned by grooves and fixed by screws (front and back). The symmetry can be controlled within 0.01-0.02mm, with 2-6 chip breakers and an X-shaped or S-shaped drill tip, suitable for different cutting materials.
Cooling System: After installing a cooling ring device, external cooling can be converted to internal cooling. Cooling water enters the internal cooling hole of the drill shank through the cooling ring and directly reaches the insert for temperature reduction. High-pressure cooling water also assists in chip evacuation, avoiding chip accumulation that affects processing.
