A new upsurge of creativity in wood is currently takingplace. Wood, with its incomparable design diversity, itsnatural character and its special atmosphere, is being re-discovered. New designs in solid wood and new interiordecorating ideas add to our living quality. Shaping wood hasa new future.
The finger joint principle is the key to this progress. It opensup many new paths in wood engineering and for interiordecoration and outfitting. Well thought-out tool systems forthe individual production of these joints in different sizes arean essential precondition. Leitz has made a majorcontribution to the development and improvement of thesetools.
The following pages contain the most comprehensive fingerjoint tool programme available from a single source. Ratherthan offering and recommending a specific finger joint toolsystem, Leitz has the correct tools for your company’s size,its machinery and its manufacturing processes. All Leitzfinger joint tools have these features in common: thehighest possible product quality and profitability, tailor-made for workshops as well as industrial companies. Make your choice!

Robust finger joint cutters (composite tools) with fixedcomponents and individually embedded finger joint knivesreduce joint breakage to a minimum.
The body shape ensures torsional rigidity. The high-qualityHS cutting materials are treated in our own state-of-the-artvacuum plants to ensure consistent hardness of the knives.
The shape of the body is matched to for the chip removalprocess and optimised. The chips are guided directly intothe suction system and do not damage the milled joints.
Compared with conventional HS cutting materials, a newspecial HS material increases working life by up to 300 %depending on the application conditions, thus considerablyimproving economy in use.

Finger jointing tools with double cutting width reducepurchasing costs for defined working widths and heightsand make repairs easier.
Cutter heads with double cutting width reduce follow-upcosts: the setting-up times are shorter and sharpeningcosts are reduced by as much as 25 percent.
Fewer interfaces at tool hubs increase finger jointingaccuracy, particularly on thick woods.
If required, the tool set can be adjusted to suit intermediatewood thicknesses by combination with finger jointing cutterheads of conventional cutting width.

A new cutting material development and coating for theprofile knives of Leitz finger joint cutter heads sets newmanufacturing performance, cost reduction and qualitystandards.
If you work with finger jointing machines, you will be familiarwith the potential problem: joints tear out, reducing theaccuracy of the joint. This is why you should switch now toLeitz finger joint cutter heads. The new coating reducesfrictional resistance and resin adhesion, which has a positiveeffect on the machine’s electricity consumption andconsequently on operating costs. The feed rate can also beincreased with the new knifes without any loss of processingquality.
All the advantages at a glance:– Exchangeable finger joint knives– Finger joint cutter head with offset knives that are parallel
to the axis and can be re-sharpened– Straight clearance flank grinding– Highly accurate bore, hub and profile knives ensure
extremely strong finger joint connections up to the finalsharpening
– Finger joint knives can be replaced if a cutter breaks– Highly economical, with a service life 4 times longer than
uncoated HS finger joint knives– Reduced grinding loss due to less cutting edge abrasion
For construction components with continuous jointsLoad group I according to DIN 68140 and DIN 1052:laminated boards (glued), solid wood construction (KVH),duo/trio beams, cross-beams, formwork carriers, post-and-rail structures.
For non-constructional components, load group II :window staves, friezes, floors, panels, wall panels, allkinds of strips, refinement/re-use of residual wood etc.

Finger joint mills (tool combination) with fixed cutters can beused for finger lengths of 10/11 mm and also for specialfinger lengths on machines with cross-cutting unit.
The cutter width corresponds to the finger joint pitch minusthe hub thickness. A flexible tool set arrangement with andwithout shoulder cutter, shoulder finger joints (butt joint) inthe centre or in the finger joint base is possible up to 150mm.
These disc cutters can be used for hard or soft wood. Therange includes tools with different diameters, finger jointpitches and numbers of knives. Finger jointing tools can beused on flat finger jointing machines (single- and double-sided) or on double end profilers. The spiral-shaped cutterarrangement minimises motor power consumption.
During repairs, all individual cutters must be ground to thesame diameter. The re-sharpening zone is 3.5 mm. HS disccutters are combined as a tool set and mounted on screwbushings (see illustration). When working on wood thickerthan 80 mm, we recommend clamping the finger joint toolsto the screw bushing with a hydro nut.

Shoulder cutters suitable for use in any position can beused for butt-joint connections. HW finger joint disc cutterscan be combined to suit the wood thickness. The numberof cutters for the wood thickness to be processed is de-termined by a grid-type structure corresponding to thefinger joint pitch. Wood thicknesses from 15 to 80 mm, andup to 150 mm in special cases, can be combined.
All versions can be produced with this tool: with shoulderfinger joints centred or in the finger joint base, or butt jointspositioned alternately or on the same level.
With a suitable tool combination, narrow strips separatedfrom thicker strips after glueing can be combined. HW discmills are put together as tool sets and mounted on a screwbushing (see illustration). For wood thicknesses of morethan 80 mm, a hydro nut is required for clamping to thescrew bushing.

Residual wood can be processed on all flat finger jointingmachines very quickly. Machine standstill times are reduced,since the tools can be attached and production can startimmediately. Thanks to constant diameters, production canbegin at once without lengthy adjustments to the machine.
The unique tool system for flat finger jointing machinesand its advantages:
– Pre-installed cutter sets for fast change-over to otherprofiles and wood thicknesses.
– A hydro-bushing with a closed clamping system forsmooth, concentrically accurate running
– The large number of knives permits high machine feedrates (up to 40 m/min-1).
– Thanks to the generous re-sharpening zone, the knivescan be re-sharpened up to 200 times, which reducesfollow-up costs considerably.
– There is only one tool body for all finger joint profiles(continuous finger joints, butt joints offset or on the samelevel in the finger joint base and also central butt joints).
– The positive cutter attachment method (no twisting of theblades) makes operation exceptionally reliable.
– Reduced finger lengths, e.g. 9.52 mm or 6.35 mm (3/8")instead of the usual 10/11 mm, mean higher wood yield.

Staves profiled with continuous finger joints after thelengthwise connection have an irregular glue line. Fingerjoint tools with so-called shoulder cutters can be used todetermine this line, which is defined as straight.
Leitz finger joint tools from our standard product range canbe combined with shoulder cutters for making shoulderfinger joint profiles for defined wood thicknesses.
The height of the rail (edge width, RdB) determines theprofile width (PB) and the finished size of the woodthickness. We offer edge joints (shoulder cutter or cutterheads) that are compatible with the ranges shown on pages6 through 9.
When using finger joint tools on spindle moulders, theregulations of the woodworking trade’s liability insuranceassociation (e.g. HBG) must be observed.
In accordance with VBG 7j §75(7) accident preventionregulations, these tools may only be used on spindlemoulders if a feed device with clamping fixture is provided.
The VR/VS backlash ratio must not exceed 0.5. Shouldercutter combinations are available upon request.
Upon request, we will also make a separate offer for fingerjoint combinations compatible with the following toolsystems: the finger joint cutter range with fixed equipmentand the finger joint cutter head range with knives that canbe re-sharpened and exchanged.
