Drilling Accessories (Page 2 of 2)
Drilling accessories are what make an air drill usable: the chuck that grips the bit, the key that tightens it, the collet that holds a cutter, the shroud that keeps swarf off the operator. Chicago Pneumatic lists keyed and keyless chucks in 6.5, 10 and 13 mm capacity, all on the 3/8 in. x 24 spindle thread its pneumatic drills use — the 24BA keyed head and the 210-2P keyless head among them. Round it out with Jacobs K30 chuck keys, 6.35 and 8 mm collets, an open drill shroud, a side handle for the CP1014, and 8- and 21-piece bit sets for wood, concrete and general use.

Keyed or Keyless
A keyed chuck clamps harder under the side load of production drilling, but the key has to be on the bench — CP lists Jacobs K32 and plain chuck keys as spares for that reason. A keyless chuck tightens by hand and is faster for frequent bit changes. Both styles come in the same three capacities, so this is a workflow choice.
Chuck Capacity and Mounting Thread
Capacity is the largest shank the jaws close on; the mount is the thread that screws onto the drill spindle.
| Chuck | Type | Capacity | Mount |
|---|---|---|---|
| 1BK | Keyed | 6.5 mm | 3/8 in. x 24 |
| 41BA | Keyed | 10 mm | 3/8 in. x 24 |
| 33BA | Keyed | 13 mm | 3/8 in. x 24 |
| J156S | Keyless | 6.5 mm | 3/8 in. x 24 |
| 510-2H | Keyless | 10 mm | 3/8 in. x 24 |
| 513-2M | Keyless | 13 mm | 3/8 in. x 24 |

Collets, Guards and Handles
A collet grips a straight-shank cutter more concentrically than three jaws and keeps the nose small for tight access; CP lists 6.35 mm and 8 mm collets for the K(C)6-7 and K(C)9-7 heads. Chuck guards for the P26 and P32, chuck covers, a CP1014 side handle and noise reducer kits round out the group. Exploded views: parts and diagrams hub.
Common Questions
What thread do CP drill chucks use? Nearly all are 3/8 in. x 24, the standard spindle thread across the CP air drill line. A chuck that will not start on the thread is the wrong mount, not a damaged one.
What capacity chuck do I need? 6.5 mm takes shanks to about 1/4 in., 10 mm to about 3/8 in., 13 mm to about 1/2 in. Buy to the largest bit you run; a bigger chuck adds nose length and weight to the drill.
Are these the same as rock drill bits? No. These chucks and bit sets are for twist drilling in metal, wood and masonry. Percussive bits thread or taper onto drill steel — see rock drill bits.
