T63 Quick Change Toolpost Accessories, Lathe Tool Holders
& Spare Parts

Optimizing toolroom and engine lathes for rapid tool swaps,
rigid setup stability, and precise height adjustments is essential for
high-efficiency metalworking. For machinists operating popular mid-sized
British and European lathes, such as the Colchester Bantam, Colchester
Chipmaster, Harrison 11" / 140, Boxford, and other
5.5-inch to 6-inch (140mm to 150mm) center-height machines, the T63 Quick
Change Toolpost System (Dickson-style T1 class) serves as the gold standard
for precision quick-change toolholding.

Replacing traditional 4-way turrets or single-point lantern
posts with a T63 quick-change system eliminates time-consuming shim adjustment
while preserving center-height accuracy across repetitive turning, facing,
boring, and parting operations. Built with precision-ground dual V-ways and an
eccentric cam-locking mechanism, the T63 toolpost collection delivers
rock-solid clamping force and precise repeatability for both HSS and indexable
carbide tooling up to 20mm and 24mm shank capacity.

Whether you need a complete 5-piece retrofit set, an
additional main block, or replacement tool holders (standard turning, V-groove
boring, and parting holders), this collection covers all essential tooling
requirements for your Colchester, Harrison, Boxford, or compatible lathe.

The T63 quick-change series is dimensionally proportioned

Key Advantages of the T63 Quick Change System

1. Sub-3-Second
   Tool Swaps: Rotate the cam lever, swap tool holders, and lock the
   handle back down. Work continues immediately without re-measuring tool
   height.
2. Eliminates
   Shim Selection: The elevation screw on each holder allows micro-fine
   height control to match the tailstock center point perfectly.
3. Vibration-Free
   Cutting: The hardened dual V-way geometry pulls the holder into two
   reference planes, dampening vibration during heavy turning and parting
   operations.
4. Hardened
   Steel Construction: Manufactured from high-tensile alloy steel, fully
   hardened and precision ground for long service life in active metalworking
   environments.

[ Step 5: Lock Height Adjustment Nut ]

1. Clean
   Mounting Surfaces: Wipe down the compound topslide to remove all
   chips, grit, and protective oil coatings.
2. Position
   the Main Block: Slide the T63 block over your lathe's compound
   mounting stud. Align the main block faces parallel and perpendicular to
   the lathe spindle axis using a machinist square.
3. Torque
   Center Nut: Tighten the central clamp nut firmly to lock the block
   onto the topslide.
4. Calibrate
   Center Height: Insert a turning tool into a holder, mount it onto the
   V-ways, and clamp the cam lever. Adjust the top elevation screw until the
   tool tip matches a dead center mounted in the tailstock quill.
5. Lock
   Setting: Tighten the knurled locking collar against the holder top
   face. The holder is now permanently set for that cutting tool.

Frequently Asked Questions (FAQ)

standard holders?

T63 standard turning holders accept tool shanks up to 20mm
or 24mm (depending on the specific holder variant), providing ample
capacity for HSS bits and indexable carbide tooling.

Q2: What center height measurement is required for the
T63 toolpost?
