20mm Alternate Shear Insert Router Bit – Solid Carbide Replacement!

We are excited to introduce our new 20MM Alternate Shear Insert Router Bit (Part No. 22006). This 2-flute, 20 mm (0.787) diameter router bit is available in a 30 mm (1.180”) cutting length and an alternating shear cutting action. Though not recommended for machining double sided materials, this insert router bit is ideal for perimeter & grooving applications of raw composite (MDF & Particle Board) materials, solid woods and difficult to machine products such as Phenolic and especially solid surface (Avonite, Corian, Wilsonart, Formica & Swanstone).

The face-mounted inserts enable a large gullet area which effectively and efficiently evacuates the material chips and aids in the heat dissipation. This is particularly important when machining heat setting materials such as Phenolic and Solid Surface materials. Standard double sided inserts are utilized and depending on the material being machined,  are available in two different carbide grades.  Reduce your tooling inventory and tooling cost substantially while improving efficiencies with a tool that offers a constant cutting diameter, economical inserts, rigid tool body construction and excellent finish results!

When it comes to machining thicker materials and when a larger diameter is acceptable, this up/down shear (compression) insert router bit is an ideal alternative to a 3/4″ solid carbide compression bit for machining double sided laminated panels, solid woods and plastics requiring a high quality, chip free finish. Initially only available with single sided inserts, this series has been completely redesigned to utilize double sided inserts providing a longer run time and cleaner cuts. With the recent design change, the cost effectiveness of this tool has increased dramatically.  Reduce your tooling inventory and tooling cost substantially while improving efficiencies with a tool that offers a constant cutting diameter, economical inserts, rigid tool body construction and excellent finish results!

Cost Comparison – Inserts vs. Solid Carbide Bits

We’ve had some interest around how the costs break down in our last post,  “Increase Productivity with Insert Compression Router Tooling”.  Here is an example using the same 6243 series (PN#6243.029.34 with insert#6243.295.00) two flute compression style insert router bit for comparison against a solid carbide two flute compression spiral (PN#6229.750.20M) to see how the costs stack up.   As you can see from the following chart the breakeven payoff for using insert tooling comes at around 45K linear feet machined. The difference in tooling cost becomes more noticeable at around 100K  linear feet machined where the cost of tooling is reduced by >50%!

If large diameter router bits (3/4″ +) is used in your cutting application, it’s important to assess the cost savings that can be achieved by using insert over solid carbide tooling.  With solid carbide bits, you must continually purchase new tools as they can only be sharpened 2 or 3 times.   In addition, often the tool life, after sharpening, is reduced to 70-80% of original tool life,  due to decreased rake angles.   Finally, after sharpening you need to compensate for the diameter change that occurred as a result of sharpening.

One of the biggest advantages of using carbide insert tooling is that you pay for the tool body one time and often get two cycles out of the same insert since the insert is often reversible.   Keeping just a box of replacement inserts on hand saves tying up cash in spare tools on the shelf.  The benefits of insert tooling, unfortunately, are not available for smaller diameter tools (such as 3/8 or 1/2″)  as they cannot be constructed in 2 flute or shear design due to space limitations on the tool body.   If you are interested in ways that you can reduce your total cost of tooling you can contact us now for more information. We also have a full service sharpening and insert grinding center with quick turn around times.

Stronger wood joints with Series 4070 Mitre Joint Cutter

GUHDO 4070 mitre joint insert style cutter head

GUHDO 4070 mitre joint insert style cutter head

Who doesn’t need stronger joints? GUHDO offers series 4070 insert cutter heads for producing accurate and incredibly strong, “Lock” mitre joints. This steel body insert cutter head is specifically designed for use on shapers and may also be used on other machines such as moulders and tenoners.

For shaper applications, the machining process involves two-steps.

1. Run the panel flat to the machine bed

2. Create a counter-profile which is achieved by running the panel vertical, tight to the machine fence

This two-step process together with glue and proper clamping, will create a lasting joint that is far superior to a simple 45 degree joint. This tool offers two replaceable carbide inserts and two serviceable groovers. Designed for machining material thickness of 14 mm (0.55”) to 34 mm (1.34”) and is ideal for solid woods, MDF and composite materials. The GUHDO 4070 insert cutter head is certainly an invaluable tool for any woodworking shop!
