To drill holes 0-40mm in diameter, we can choose carbide drill, with good solidity and drilling performance, generally applied in high speed drilling equipment, in boiler, bridge, shipbuilding, wind power, nuclear power etc. In comparison with twist drill, efficiency is increased 3 times.
And sometimes when drilling holes it’s not necessary to cut off all the metal with chips and shaving. So the most economic way is to use trepanning drill, by driving drills into socket and turn the shank, round slots can be made by removing the metal in form of disk and leaves a hole on steel plates.
This method can reduce material waste and machine power consumption. When the sample is removed for performance testing, the trepanning drill is the unique tool which can’t be replaced by others.
ADVANTAGES:
Drill as deep as you want. There’s virtually no limit to the depth of the hole.
Save core for reuse. As the trepanning tool feeds into the work piece, the trepan bit or insert cuts a groove the width of the bit and a solid metal core remains. Because only the width of the bit is cut, trepanning is faster and more efficient than drilling with spades or indexable drills. Remove and reuse the metal core for other operations and cut your material costs even more.
Works on a variety of equipment. Muskegon Tool can develop your trepanning tool to work on horizontal boring mills, engine lathes, turret lathes, deep hole boring machines and other machines.
Simplifies maintenance. Trepan bits and wear pads can be replaced without replacing the head and stem so you spend less on tooling and labor costs. Shank type bits are stocked for immediate shipment.
