Tailstock Stationary Tool Holders
- Wood drilling applications, i.e., pool cues, woodwinds, etc. in the tailstock of wood or engine lathes.
- Metal drilling applications in CNC lathes with a powered tailstock
For wood drilling, tailstock tool holders offer a much stronger, more secure mounting of a gun drill than a "Jacobs" type drill chuck. The gun drill has a simple rear air driver for quick drill change as the tool holder connected to the air supply remains in the tailstock.
For metal drilling applications in CNC's with a powered tailstock, a longer gun drill can be fitted, plus it provides more clearance and indexing options than what's possible in the turret.
Pricing is $150.00 each Order / re-order gun drills to the driver specification below:
Our # | Shank & bore | Recommended driver size |
TH-19 | #2 MT x 5/8" bore | 5/8" x 1 1/2" long w/ 1" central flat * |
TH-20* | #3 MT x 3/4" bore | 3/4" dia. x 1 1/2" long w/1" central flat * |

TH-21 | #4 MT x 1" bore | 1" x 2 3/4" long w/2" central flat or "C" driver |
Toolholders have a 1/8" NPT side-air thread. For wood, air at 60-100 psi is recommended. For metal drilling in a CNC, our Spraymist System or high pressure coolant can be used. Each toolholder is supplied with a 1/8" x 1/4" NPT adapter,
internal "O" ring, Allen wrench, and two spare "O" rings. Other NPT & BSP adapters are available. The internal "O" ring is placed at the bottom of the bore and the gun drill's driver is locked against it to make a tight seal.
