Air Operated Drilling Unit
Air Operated Drilling Unit BE(S)21
The BE (S) 21 is a low-cost pneumatic drilling unit with feed but without hydraulic damper and without subdivision into rapid and working feed.
The feed rate is controlled by a set screw at the air inlet throttle.
The construction is extremely compact with an outer diameter of only 45 mm.
The stainless version is particularly suitable for applications where moisture and/or splash water are present.
