HOLEMAKER HSS M2AL ANNULAR CUTTER 14MM X 50mm

Description

Product Introduction
This 14mm × 50mm HSS M2AL annular drilling tool produced by VANGUARD INDUSTRIAL, also commonly known as high-speed steel hollow core drill or steel plate drill, is an efficient specialized tool for industrial metal drilling:
Core parameters: The drilling diameter is 14mm, the maximum effective cutting depth is 50mm, and it is forged with high-performance M2AL aluminum containing high-speed steel. The overall strength and hardness are much better than ordinary high-speed steel drill bits, and the impact resistance and wear resistance are excellent.
Performance characteristics: It adopts a multi group spiral cutting edge structure, only cutting the annular edge of the hole. Compared with the traditional solid Fried Dough Twists drill, the cutting amount is significantly reduced, the drilling efficiency can reach 8~10 times of the ordinary drill, and the drilled hole wall is smooth without burrs, without secondary finishing. It is compatible with the vast majority of magnetic drills, magnetic seat drills, vertical bench drills, milling machines and other equipment, and can easily complete drilling operations for various metal plates such as steel, stainless steel, aluminum, copper, etc. It is widely used in steel structure engineering, rail transportation, shipbuilding, mechanical assembly and other fields.
🛠️ Usage
Preparation in advance
Mark the drilling points on the surface of the metal sheet to be processed in advance, firmly fix the workpiece to avoid displacement during operation, clean the rust, welding slag, and debris in the processing area, confirm that the cutting edge of the drill bit is not damaged or curled, check that the magnetic seat of the magnetic drill is firmly attached, and that the equipment is operating normally.
Installation and debugging
Fully insert the handle of the drill bit into the drill chuck and lock it, then install the positioning pin to confirm that the drill bit has no offset in coaxiality. Adjust the drill speed according to the material and thickness of the processed plate: choose medium and low speeds for processing ordinary carbon steel, and further reduce the speed for processing hard metals such as stainless steel to avoid overheating and wear of the cutting edge.
Drilling operation
Align the drill bit with the marked point, keep the drill bit completely perpendicular to the surface of the workpiece, start the drilling rig smoothly, apply axial feed pressure evenly and slowly, and continuously introduce specialized metal cutting coolant throughout the process. Priority should be given to using internal cooling to allow the coolant to reach the cutting edge, taking away the high temperature generated by cutting and greatly extending the service life of the drill bit. If processing deep holes, the drill bit can be intermittently lifted to discharge metal chips and avoid chip jamming and blade breakage.
Closing operation
After drilling is completed, stop the feed first and wait for the drill bit to completely exit the workpiece before shutting down the equipment. Clean the surface of the drill bit of chips and residual coolant, confirm that the cutting edge is not worn or deformed, and store the drill bit in a dry and ventilated environment to avoid moisture and rust affecting subsequent machining accuracy.
