HOLEMAKER HSS M2AL ANNULAR CUTTER 18mm X 25mm

Description

Product Introduction
This 18mm × 25mm HSS M2AL circular drilling tool produced by VANGUARD INDUSTRIAL, also commonly known as high-speed steel hollow steel plate drill or core drill, is a lightweight and efficient metal drilling tool:
Core parameters: The standard drilling diameter is 18mm, the maximum effective cutting depth is 25mm, and it is forged with aluminum M2 high-performance high-speed steel. Compared with ordinary high-speed steel, it has better red hardness, impact resistance, and wear resistance. It is also less prone to the problem of edge annealing and rolling during long-term operation.
Performance characteristics: It adopts a multi group spiral cutting edge structure, and only cuts 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 most magnetic drills, bench drills, milling machines and other equipment, and can easily complete drilling operations for various metal plates such as thin steel plates, stainless steel, aluminum, copper, etc. It is very suitable for shallow hole rapid processing in steel structure assembly, sheet metal processing, mechanical and electrical installation and other scenarios.
🛠️ 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, and check that the supporting drilling rig is operating normally.
Installation and debugging
Fully install the Weldon standard shank of the drill bit into the drill chuck and lock it, and match it with the positioning pin. Confirm that the coaxiality of the drill bit is not offset, and adjust the drill speed according to the material of the processed plate: choose medium speed for processing ordinary carbon steel, and reduce the speed appropriately 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 metal cutting coolant throughout the process. Prioritize using internal cooling to allow the coolant to reach the cutting edge, take away the high temperature generated by cutting, and greatly extend the service life of the drill bit. If there is poor chip removal during the machining process, the drill bit can be briefly lifted to remove 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.
