Where this product is used

Annular cutters remove only a thin ring of material rather than drilling the full core to swarf — they are faster and produce a cleaner hole than twist drills in thick plate.

• Accurate hole cutting in steel plate and structural sections using mag drill machines
• Structural steel fabrication, boilermaking, and heavy engineering
• Mining, rail, and civil engineering hole cutting in thick plate

Key specifications

Selecting the right option

Select cutter diameter and cutting depth to suit the hole specification. Annular cutters require a magnetic drill base (mag drill) — they cannot be used in standard drill presses without modification. Cutting depth must be confirmed against the plate thickness; longer cutters suit thicker plate. Use cutting oil on steel plate.
