Anchor Drill Size Chart (Masonry Bits)
The masonry drill bit size for each anchor diameter, and the minimum embedment depth.
| Anchor diameter | Drill bit (in) | Min embed (concrete) | Anchor types |
|---|---|---|---|
| 1/4 | 1/4 | 1-1/8 in | Wedge, sleeve, Tapcon |
| 5/16 | 5/16 | 1-1/4 in | Sleeve, hammer-set |
| 3/8 | 3/8 | 1-1/2 in | Wedge, sleeve, drop-in |
| 1/2 | 1/2 | 2-1/4 in | Wedge, sleeve |
| 5/8 | 5/8 | 2-3/4 in | Wedge, drop-in |
| 3/4 | 3/4 | 3-1/4 in | Wedge, drop-in |
Drill the hole 1/2 in deeper than the embedment and blow out the dust — a dusty hole cuts anchor capacity sharply.
