KAKA INDUSTRIAL BS-712R Metal Band Saw, 7 x 8.25 in Swivel Bow

The KAKA INDUSTRIAL BS-712R is a stationary horizontal metal band saw designed for fabrication shops, maintenance facilities, and repair garages. It handles cutting tasks across a range of structural shapes, pipe, bar stock, tubing, and plate. With a 7-inch round and 7 x 8.25-inch rectangular capacity at 90 degrees, it provides ample clearing room for standard metalworking materials.

A standout functional feature is the swiveling saw bow, which rotates from 90 to 45 degrees. This allows you to set up angled miter cuts directly on the machine without shifting long metal bars across your workspace. For angled work at 45 degrees, the saw accommodates 5-inch round and 3.33 x 5.5-inch rectangular pieces.

The cutting mechanism runs on a 1.5 HP (1.1 kW) single-phase motor capable of 115V or 230V operation at 60Hz. It comes prewired for standard 115V circuits. Power transfers through a V-belt drive system with two pulley wheels, offering four discrete speeds (27, 41, 59, and 78 MPM) to match materials like aluminum, mild steel, or solid bar. Operational control is managed with a hydraulic feed control, feed ON/OFF valve, an automatic shut-off tab, adjustable bearing blade guides, and an integrated coolant system.

Weighing 407 pounds net (525 pounds gross), this is a heavy-duty stationary machine that requires dedicated floor space, though the included stand and wheels help with repositioning. While the V-belt system provides dependable speed settings, it requires manual belt repositioning across pulleys rather than an electronic dial.

Verdict: The BS-712R is an excellent choice for metal fabricators and repair shops needing solid cutting capacity, integrated coolant, and miter flexibility on standard single-phase power. It provides reliable, controlled cuts across various structural metals.

• 90-Degree Cutting Capacity: 7 in round, 7 x 8.25 in rectangular
• 45-Degree Cutting Capacity: 5 in round, 3.33 x 5.5 in rectangular
• Motor: 1.1 kW / 1.5 HP single-phase, 115V/230V, 60Hz (prewired 115V)
• Blade Speeds: 27, 41, 59, 78 MPM (at 60Hz)
• Blade Size: 20 x 0.9 x 2362 mm
• Drive System: V-belt drive with two pulley wheels
• Weight: 407 lb net weight, 525 lb gross weight
• Included Hardware: Stand, wheels, vise, coolant system, hydraulic feed control

A great fit if you:

• Work with structural tubing, pipe, plate, or bar stock up to 7 x 8.25 inches.
• Need to make 45-degree miter cuts without wrestling long stock around the shop.
• Rely on standard 115V workshop outlets but want the option to wire for 230V later.
• Require a built-in coolant system and hydraulic downfeed for steady cutting.

Consider something else if you:

• Need a lightweight, highly portable saw that one person can lift into a truck.
• Require variable-speed adjustments without manually repositioning belts on pulleys.
