Double-Ended Long Spiral Router Bit for Thick Hardwood Cutting

8mm Spiral Cutter Bit in Action

Features of Carbide Spiral Router Bit Set for Thick Wood Cutting

• The blade is made of top-level tungsten steel; the superfine particulate tungsten base materials features of tough and durable. The superfine tungsten is prior to regular tungsten on the performance.

• Since the blade is sharp, the spiral bit set can cut with high speed and offer you a nice clean cut. 

• Large single flute prevents the wood chips from sticking to the blade and has them to be removed smoothly, which increases the cutting efficiency. In addition, the big spiral angle helps to quickly removing chips, reduce chip jams and cutting resistance, and improve cutting surface finish.

• The two ends of the carbide spiral cut bit are hold by two spindle motors; This makes the cutter less likely to break even when cutting through wood over 100mm. So, it has a long service lifespan.

• The tool shank is round in shape and chamfered. Therefore, it can be securely fastened, resistant to slipping, and easy to install and uninstall. 

• Unique design on blade back; By optimizing the shape of the blade back, the contact area between it and the workpiece has been minimized, thereby reducing friction and heat generation during the cutting operation.

Carbide Spiral Bit Package

Each spiral cutting router bit is packed in an individual plastic case; this kind of package can protect the tools very well and prevent them from damage. Before shipping, we will wrap them with bubble film and put them in a carton. Finally, we wrap the cartons with stretch film to make them waterproof.

Useful Tips for Using Spiral Cutting Bit Properly

• When installing the spiral bit, make sure it rotates in the correct direction to avoid bad cut due to the upside down ends.

• The shorter the tool hangs out of the collet, the better; If the bit extends too long, the spindle RPM, feed rate, or cutting amount should be appropriately reduced.

• If abnormal vibration or noise occurs during the cutting process, please reduce the RPM and cutting amount until the situation improves.

How to Select Proper Spiral Saw Bit For Your Production Need

Choosing the proper tool model helps to reduce production costs and increase output.

Tips on Choosing the Blade Length

• According to the material thickness or cutting depth, we add 5mm or 10mm to them then we get the ideal blade length. For example, if the wood is 70mm thick, the ideal blade length should be 75mm or 80mm.

• If the material to be cut is a multi-layer board, we should calculate the total cutting depth and also consider whether the board is bulging or the table top is uneven.

• For tools with a shank diameter over or equal to 8 mm, the ideal blade length can be appropriately extended by a few millimeters.

Tips on Selecting the Blade Diameter

• The factors we should take into consideration include: the fineness of the product, working efficiency and the hardness of the material to be cut.

• The general principle is to choose a coarser tool as much as possible while ensuring the finished precision and meeting the nesting needs. The coarser the tool, the better the chip removed, the faster the cutting operation, and the less likely it will break or stick. 

Useful Tips on Cutting With 8mm Spiral Router Bit

• After switching on the machine and before starting the cut, please check the machine's feed rate, spindle RPM, and starting point. Choose a reasonable speed according to different tool models to prevent the cutting bit from breaking due to excessive speed.

• If the tool is a new model and this is your first time using it, it is recommended to start with a lower speed first, wait for the machine to run a while, observe the spindle sound and vibration, and then adjust the speed and other parameters appropriately to optimize processing speed. The appropriate feed rate is crucial to improving product finishs and tool life.

FAQs about Best Spiral Router Bit For Thick Wood Cutting And Hardwood Cutting

Q: Can We Use This Bit on A CNC Router Machine?

A: No, you can’t. The spiral router bit with two ends can not be mounted on a CNC router machine to cut. Because of that, the blade is in the middle section. This tool should be used with a specific thick hardwood cutting CNC machine; so that its upper and lower ends can be hold by the upper and lower spindles of the machine, and perform cutting via the blade in the middle section.
