Key Features:

• 180 mm in a single pass — designed for thick base plates, wind-power flanges, heavy machinery frames and stacked plate work.
• Carbide tips, not HSS — holds an edge in stainless 304/316, wear plate and cast iron; typically 2–3× the life of HSS at higher feed rates.
• Deep-hole flute geometry — wide, polished chip channels clear long chips and reduce binding at depth; external coolant reaches the tip.
• 3/4″ Weldon shank — drops straight into most of magnetic drills. No adapter.
• Clean bore, no reaming — annular cutting leaves a close-tolerance, burr-free hole ready for 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.
