Preparing holes for standard M16 bolts using traditional 18mm twist drills is often a slow and exhausting process. The heat generated during solid drilling often leads to "edge burning," requiring frequent tool changes and slowing down the entire fabrication line. For site workers, the high physical pressure required for a solid 18mm drill increases fatigue and the risk of inaccurate hole placement.
A solid 18mm drill must remove a massive volume of metal, concentrating all that stress and heat at the tip. In thick steel plates, chips often get trapped in the deep flutes of a twist drill, causing friction to spike and the drill bit to snap. Without a hollow center to allow for easier chip flow and cooling, tool life is severely compromised in high-volume production.
Our 18x30mm HSS-M2 Annular Cutter tackles these issues by only cutting a thin 18mm ring. This removes significantly less material, reducing torque requirements by up to 60%. As seen in the image, the fully ground helical flutes and specialized tooth geometry ensure that chips are ejected effortlessly, keeping the tool cool and the cutting speed consistently high.

Structural Steel Connection: The 18mm diameter is the international standard clearance hole for M16 bolts in I-beams and columns.
Bridge Construction: Perfectly suited for drilling gusset plates and reinforcement layers up to 30mm thick.
General Metal Fabrication: Ideal for creating high-precision holes in mild steel, aluminum, and copper plates.
Magnetic Drill Compatibility: Fully compatible with Euroboor, Alfra, Hougen, and all standard magnetic drill presses.
Pilot Pin Synergy: Pair this 18x30mm cutter with a 6.35x77mm pilot pin for automatic centering and slug ejection.
Standard Depth Advantage: The 30mm cutting depth provides the versatility to handle single thick plates or multiple thin-stacked plates in one pass.
Coolant Efficiency: Always use internal pressure lubrication; the hollow center of the 18mm cutter acts as a direct conduit to the cutting zone.
Q: Is 18mm the right size for an M16 bolt?
A: Yes. Standard engineering codes require a 2mm clearance for structural bolts. An 18mm hole ensures smooth bolt entry and allows for thermal expansion in the structure.
Q: Can I use this 30mm depth cutter on a 10mm plate?
A: Absolutely. While it can cut up to 30mm, it works exceptionally well on thinner plates, providing a much cleaner finish than a twist drill.
Q: Why does the cutter in the image have two flats on the shank?
A: That is the Weldon Shank standard. The two flats allow set-screws to lock the tool securely, preventing it from spinning under the high torque of 18mm drilling.
Q: How many holes can I drill in standard A36 steel?
A: With proper cooling and steady feed, you can expect 300-500 precision holes before needing to re-sharpen the M2 edge.
