Landis Collapsible & Solid Adjustable Taps

Collapsible & Solid Adjustable Taps

Collapsible Taps
All three models of collapsible-style taps (ALT, LL and LLSR) have a mechanism that collapses the chasers into the tap head upon thread completion, allowing direct withdrawal of the tap from the workpiece. Taps can be furnished for stationary and revolving applications.

ALT Collapsible Taps
Five standard tap bodies and 33 standard tap heads enable ALT taps to produce 1-1/4″ to 13-1/4″ I.D. and 1-1/4″ to 12″ nominal NPT and BSTP pipe threads. Recommended where wide range of work requires the versatility and wide range coverage offered by detachable tap heads. Download PDF

LL Receding Chaser Collapsible Taps
A receding chaser type tap primarily intended to produce longer length American Petroleum Institute (API) threads. Can also be used to cut NPT and BSTP taper pipe as well as straight threads. Four bodies with 26 standard tap heads allow 1″ to 12″ nominal pipe sizes to be tapped. Download PDF[/cs_text]

2 LLSR Collapsible Taps
A receding chaser type tap for use where overall length restrictions prevent the use of the longer LL Tap. The 2 LLSR’s overall length is 10-1/16″ regardless of the tap head size used. The 2 LLSR tap body can be supplied with 1-1/4″, 1-1/2″, and 2″ size heads to produce threads on 1-1/4″, 1-1/2″, and 2″ NPT, BSTP, and API line pipe, without chaser leave-off marks.

Solid Adjustable Taps
Our solid adjustable taps are recommended for high production tapping on reversing spindle machines and for automatic screw machines where limited length clearance prohibits the use of a collapsible tap. These taps also are ideal for hand sizing and salvaging previously tapped threads.
Our solid adjustable taps are precision tools made from alloy steel. The chasers are held securely against tapered seats on the plunger and are supported on all sides. This gives the rigidity needed for accurate threads. The chasers are made from high-speed steel. The thread form and all supporting or locating surfaces are precision ground after hardening to ensure accuracy and longer chaser life. The chasers can be reground to lower overall tooling costs.
