This jig has been made for a pre cut 4x4 dice blank, which would actually be a 3.5 inch block. The dice blank fits into its pockets and the jig gives accurate placement for dice pips to be drilled. The Jig has 2 pockets, allowing the pips for numbers 1, 2, 3, 4, and 5 to be drilled via the 5 hole pocket and the pips for number 6 to be drilled via the 6 hole pocket.
The pip holes are 1 inch in diameter and would allow for and drill bit up to 1 inch. However, a plunge router with a bushing kit and round nose router bit is recommended for a professional look.
The Jig is made from high quality MDF and should have a long life when used with the correct tools. The jig has been made to precise specifications and should give perfect pips every time when used with correct tools. The jig's pockets are made slightly larger to account for the variation in sizing with 4x4 blocks. If the block doesnt fit due to wetness, swelling or humidity (which occurs in certain parts of the country), the blocks should be sanded down to 3.5 inches.
