BM21 Portable Beveling Machine

Reduce your costs and lay the foundation for high-quality welds with the Steelmax BM21 and BM21-SS ( for use on stainless steel). Inaccurate bevels and poor weld preparation are often the root cause of weld defects and excessive welding costs. Both machines utilize a high speed rotary milling head with ten carbide inserts to produce precise bevel angles from 0 to 60 degrees that dramatically improve fit up and all subsequent welding operations. The BM21-SS, specifically designed for use on stainless steel, also utilizes a lower speed motor and all stainless contact surfaces to eliminate contamination of the stainless steel work piece.

Unlike flame or plasma cut weld preparation, the BM21 and BM21-SS produce no heat affected zone or distortion of the work piece. These portable tools can be carried anywhere and eliminate time consuming and costly material handling associated with moving plates around the shop to stationary burning and milling machines.

The BM21 and BM21-SS feature an ergonomic design that includes vibration dampening technology to protect the operator and the machine during heavy continuous operation. Automatic thermal overload protection circuitry protects the motor from premature failure, providing a reliable tool that can withstand the toughest jobs. The BM21 and BM21-SS can be used on plate and pipe without any additional accessories.


  • Single milling head equipped with 10 indexable carbide prodcues weld-ready bevels quickly and efficiently with low operator effort
  • Fast and easy exchange of inserts with no need for special adjustment
  • Working range from 0 to 60 degrees with continuous angle adjustment
  • Simple bevel angle and bevel width setup
  • Advanced vibration isolation protects both the operator and the machine
  • Universal guide plate requires no additional accessories for beveling both plate and pipe
