Product Group Page - Steelbor / Annular Cutters
Steelbor Annular Cutters are used to create accurate connection holes in metal with magnetic drilling machines. They remove a ring of material and eject a slug, rather than drilling out the full hole diameter, helping users create larger holes faster and with less cutting load than traditional twist drilling.
The range includes SilverMax HSS Cutters for everyday applications, CarbideMax TCT Cutters for tougher materials, ULTRA TCT Cutters for extreme applications and XL options for deeper cutting requirements. All Steelbor Annular Cutters use the universal Weldon shank for compatibility with a wide range of magnet drills.
They give users a clear choice of cutter type by material, depth and application, helping improve cutting speed, hole accuracy and jobsite efficiency.
Here are the 5 Product Families within this Product Group
Carbidemax TCT
Steelbor CarbideMax TCT Cutters are used for fast, accurate broaching in tougher metal applications. They are fitted to magnetic drilling machines and cut a ring of material, producing clean connection holes without drilling out the full diameter.
Tungsten carbide teeth make them a strong choice where extra cutting performance is needed compared with everyday HSS cutters. They are useful for structural steelwork, fabrication and site drilling where speed, durability and hole quality matter.
Built with a Weldon shank, CarbideMax TCT Cutters are compatible with suitable magnetic drilling machines. They help users cut larger holes faster, reduce cutting load and keep heavy holemaking work moving.
Other
Steelbor Annular Cutters / Other covers supporting items, specialist cutters or related products that sit outside the main HSS, TCT, ULTRA and XL cutter families. These products help users maintain, adapt or complete their magnetic drilling setup.
Annular cutting depends on the correct combination of cutter, pilot, machine and application. Smaller support items can be important for accurate cutting, slug ejection and reliable performance on site or in the workshop.
Used as part of the Steelbor magnetic drilling system, these products help keep cutting work organised, compatible and ready for different materials, depths and holemaking requirements.
HSS
Steelbor HSS Cutters are used for everyday annular cutting with magnetic drilling machines. They provide a practical solution for creating clean, accurate connection holes in general steel drilling applications.
HSS cutters are a strong choice for routine fabrication, workshop and site work where users need reliable performance without moving into specialist cutter types. They remove a ring of material and eject a slug, helping create larger holes more efficiently than traditional twist drilling.
Built with a Weldon shank, SilverMax HSS Cutters fit suitable magnet drills and form part of the wider Steelbor system. They help users drill accurately, reduce cutting load and keep standard holemaking tasks moving.
Ultra TCT
Steelbor ULTRA TCT Cutters are used for extreme or demanding annular cutting applications. They are designed for users who need higher performance when drilling tougher materials or more challenging steelwork.
The ULTRA range gives users a more specialist cutter option within the Steelbor system, helping improve cutting performance where standard cutter choices may not be enough. Tungsten carbide teeth and ULTRA coating support durability and cutting efficiency in harder applications.
Built with a Weldon shank, ULTRA TCT Cutters are compatible with suitable magnetic drilling machines. They help users create accurate connection holes in demanding conditions, while keeping the speed and control of annular cutting.
XL
Steelbor XL Annular Cutters are used with larger magnetic drilling machines that take the 31.75mm Weldon shank. They are designed for heavier-duty broaching applications where the machine, cutter size and shank connection need to match.
The larger shank size gives the correct interface for compatible high-capacity magnet drills, helping users work with larger cutters and more demanding holemaking setups. This is important when standard 19.05mm Weldon shank tooling is not suitable for the machine or application.
Steelbor XL Annular Cutters support accurate connection hole creation in heavier steelwork, while keeping the cutter matched to the correct magnetic drilling system.
