An assembly for accurately and easily drilling holes at a desired angle relative to a work piece. The assembly includes a housing having a rotatable drill guide therein. The drill guide includes a tang extending out from a side of the housing so that it can be manually rotated to position the drill guide in a desired orientation. Angular markings are provided on the side of the housing to align with a groove on the tang. The drill guide is biased towards an insert guide to create an opening whose size is adjustable for receiving drill bits of varying sizes.
