The usage of an annular cutter

An annular cutter (Core drill) can cut all kinds of steel, steel pipe, cast iron, stainless steel, aluminium, copper, and various non-metallic materials.

Type

Annular Cutter Set Method of Application

1. Installation method:

• Weldon Shank (1) The handle of two planes aimat thetwoscrewholeson the drill spindle， with a hex wrench to tighten and leaving a gap of 0.2-0.3 mm, Back and forth with your hand to confirmsocket headscrewperpendicular to the two planes, then screw down the screws.
• Universal shank (2) The handle of two planes aims at a steel ball within the drill chuck, which is then loaded into the chuck. Universal shank can also be used with socket head screws, as long as the socket head screw is perpendicular to the two planes.
• Fein Shank (3)Turn on the insurance ring of the main shaft clockwise to the right way, let the handle end insert directly, rotate in a small range until the steel ball enters the hole.

2. Recommended cutting speed for high-speed steel annular cutter:

3. Feed speed: The recommended feed speed is 0.08-0.12mm/R or 0.6-1.0 mm/sec. Different feed speeds will cause different chip effects and affect the performance of chip removal.

4. Positioning: Chisel a positioning point in the centre of the position to be drilled or mark a “cross” line with an alloy needle to ensure the accuracy of the drilled position. Note that when using the centre chisel to hit the positioning point, please make sure that the centre chisel is perpendicular to the surface of the workpiece to avoid affecting the smooth discharge of the cutting core

5. Start to drill: Make sure the magnetic drill machine’s button is clean before powering on. When starting to drill, turn on the switch for the coolant liquid. First, feed slowly, then at the normal speed after drilling 1-2mm.

6. Finish drill: Turn off the power and use the hook to remove the chips on the cutter after it stops.

[Notice] The following actions will help to reduce or slow the wearing and fracturing of the cutter.

• When drilling steel parts, please ensure enough cooling and use metal cutting fluid.
• Good rigidity of the drill pipe and the guide rail gap can improve the precision of drilling and the life of the bit.
• Please make sure flat and clean between the magnetic holder and artifacts.
• Before cutting, lock all parts securely.
• Drilling at the start and at the end, the drilling feed should reduce by 1/3
• For a large amount of fine powder material that occurs in the drilling,such as cast iron, cast copper, etc., compressed air instead of coolant liquid can help chip removal.
• Please remove the chips on the cutter to ensure smooth chip removal.

Troubleshooting the VEVOR Annular Cutter

The solutions of the chip core stuck:

Use a nonmetallic material, lightly slapping the drill or lightly pressing the core material repeatedly, to make it loosen to pop up, remove the bit, and tap the thimble so it is out.

The wearing of tools:

Under normal cooling, when the chip appears blue-black color, it needs to check the drill bit blade; when the maximum wear width is 0.5mm, it requires grinding.
