Key Features:

• 150 mm depth, one pass — for thick flanges, base plates, beam webs and heavy weldments; no step drilling, no pilot hole.
• Carbide edges for hard materials — cuts stainless 304/316.
• Chip control at depth — deep, polished flutes with external coolant delivery clear long chips and prevent the cutter from binding.
• Fits every magnetic drill — standard 19.05 mm Weldon shank, no adapter needed.
• Accurate, burr-free bore — annular geometry produces a clean hole that often needs no deburring before bolting or tapping.

Application Fields

• Structural steel and heavy fabrication
• shipbuilding and offshore structures
• flange and base-plate drilling
• crane and heavy equipment manufacturing
• plant construction
• maintenance and on-site drilling

Operation Notes

• Use proper cutting fluid for cooling and lubrication during drilling.
• Check clamping condition before operation for safety.
• Recommended for metal plate & tube drilling, not suitable for non-metal or ultra-hard alloy materials.
