GBC SB320 — Blades & Consumables
Outside bevelling blade holders for the GBC SB320. The two lines split by the angle the holder presents: 30° and 37.5°. The angle is fixed in the holder, not adjusted.

Advantages
Angle Fixed In Holder
The bevel angle is not set on the machine, it comes with the holder — removing both setting error and operator-to-operator drift.
Ordered By Procedure
30° and 37.5° give 60° and 75° V grooves when paired, so the order follows the angle the welding procedure defines.
Separate From Cutter
The holder carries the cutting tool that wears, and stays on the machine when the cutter is renewed.
A Two-Line Decision
One angle in production means one holder; two procedure angles mean both lines held in stock.

Features
- Outside bevelling blade holders for the GBC SB320
- 30° holder — a 60° V groove when two faces meet
- 37.5° holder — a 75° V groove when two faces meet
- The angle is fixed in the holder; nothing is set on the machine
- Groove geometry survives a change of operator
- The holder carries the cutting tool and defines the angle
On the SB320 it is the blade holder that fixes the bevel angle. The holder presents the blade to the work at a set angle, and because nothing is dialled in on the machine, the groove geometry survives a change of operator. There are two holders in this family. K20721 gives a 30° outside bevel: two such faces meeting make a 60° V, which keeps weld volume down on heavy sections. K20723 gives 37.5°, making a 75° V when paired and opening up electrode access. Which one to order is not a preference — it follows the groove angle written into the welding procedure. Both lines are listed as holders, meaning the part that carries the cutting tool and defines the angle, separate from the cutting edge that actually wears. The product data does not state a material group for these codes, so the carbon-versus-stainless split is not made at the holder; that decision is handled on the cutting side. A line running both angles keeps both holders and swaps as the procedure changes; a line running one angle needs one.
