Product Description
37000 Series TCT Rail Annular Cutter — 30% Longer Life for Rail Drilling Applications
The 37000 Series TCT Rail Annular Cutter is a carbide-tipped annular cutter engineered specifically for cutting rail track, including Standard Rail Rack and Hardened Rail Rack. Designed for contractors and rail maintenance professionals who demand maximum tool life in demanding environments, this cutter delivers 30% longer service life compared to standard rail cutters. Featuring a twist-lock shank, it is compatible with most rail drills and is optimized for machines running above 300 RPM. A 1" depth-of-cut pilot pin (Code: PILOTS) is included to ensure accurate, repeatable hole placement.

Unlike standard HSS rail cutters, the 37000 Series uses carbide tips specifically formulated for the extreme hardness of rail steel, resulting in measurably longer tool life and reduced downtime between cutter changes. The twist-lock shank interface ensures secure, repeatable mounting across the majority of rail drill platforms without requiring adapters.
Key Features & Benefits
Carbide-Tipped Construction
Carbide tips provide superior hardness and heat resistance compared to standard high-speed steel cutters, making them well-suited for the abrasive, high-strength steel found in rail track. This directly translates to fewer tool changes and lower cost per hole on the job.
30% Longer Tool Life
The 37000 Series is engineered to deliver 30% longer life than standard rail cutters, reducing the frequency of cutter replacement on extended rail projects. For contractors working on large-scale rail installations or maintenance programs, this improvement meaningfully reduces consumable costs and downtime.
Twist-Lock Shank Compatibility
The twist-lock shank design is compatible with most rail drills, allowing straightforward integration into existing equipment without the need for special adapters. This broad compatibility makes the 37000 Series a practical choice across a variety of rail drilling setups.
Optimized for High-RPM Rail Drills
Carbide-tipped construction makes the 37000 Series suitable for rail drills operating above 300 RPM, where standard HSS cutters may underperform or wear prematurely. This allows operators to run at higher speeds without sacrificing cutter longevity.
Includes 1" DOC Pilot Pin
Each cutter ships with a 1" depth-of-cut pilot pin (Code: PILOTS), ensuring accurate hole positioning and consistent depth control from the first cut. Having the pilot pin included reduces setup time and eliminates the need to source compatible pilots separately.
Wide Diameter Range
Available in twelve diameters from 3/4" through 1-1/2", the 37000 Series covers the full range of common rail drilling requirements. Contractors can standardize on a single cutter series across multiple hole sizes, simplifying inventory management.
Common Applications
Standard Rail Rack Drilling
The 37000 Series is designed for drilling standard rail rack, providing clean, accurate holes for rail fastening and bonding applications.
Hardened Rail Rack Drilling
Carbide-tipped construction allows the 37000 Series to cut through hardened rail rack where standard cutters would wear rapidly or fail prematurely.
Rail Track Installation
Suitable for new rail track installation where precise, repeatable hole placement is required across large volumes of rail sections.
Rail Track Maintenance and Repair
Ideal for maintenance crews drilling replacement fastener holes or bond wire holes in existing in-service rail track.
Compatible Materials
- Standard rail steel (Standard Rail Rack)
- Hardened rail steel (Hardened Rail Rack)
