Starrett A1 Arbor 3/8 is rated 2.8 out of 5 by 5.
Rated 4 out of 5 by from It's an arbor... This is a standard small holesaw arbor. Note it's the larger, 3/8" - 10mm, chuck version. I'd still prefer it to have flats for a 17mm spanner so the holesaws can be removed easily. They can get very tight given they are only screwed on.

Rated 1 out of 5 by from Rubbish Bought this as lost my previous arbour. Opened the packet and put my hole saw on it then realised there was no nut to tighten it on inside the packet. I have the nut from the one I lost only to discover it won't fit. Very frustrating.

Rated 3 out of 5 by from Good arbor, but grub screw fle I used the arbor with a 20mm bi-metal cutter to cut 1.5mm mild steel sheet. It cuts very well, but the grubscrew used to secure the drill within the arbor must not have been tightened and it flew out never to be seen again. Hence poor reliability figure.

Rated 1 out of 5 by from Awful Bought one as my last one let me down, within 3 holes the pilot drill had snapped and could not release it as it was jammed in. Wouldn't buy again
