Good Value

Works well for the price. The OD was slightly tight in my housing but a little polishing fixed it. Inner diameter is accurate.

Solid Construction

The steel is hard and well finished. No burrs on the edges which saved me time during installation. Highly recommend for workshop projects.

Perfect Guide

Fits my drill press table perfectly. Provides excellent guidance for the drill bit and reduces wander significantly. Very satisfied.

Excellent Precision

Used this for a custom jig setup and the tolerance was spot on. The steel feels very durable and holds up well under repeated drilling.
