Double flute Straight bit

In choosing a straight bit for any application, always select one with the shortest cutting edges and the shortest overall length that will reach the required cut depth. Excessive length intensifies deflection and vibration, which degrade cut quality and lead to tool breakage.

Use a two-flute bit where fine finish is paramount. Two flutes balance the bit, eliminating vibration that degrades the cut finish.

Two cuts per revolution yield a smooth surface, but feed rate is slightly reduced.

This router bit has a 6.35mm shank (shaft) that will fit most small routers. Please ensure that you select a router bit with a shank (shaft) size that will fit into your router collet.

 

PRO-TECH router bits are manufactured in Taiwan.

To use router bits safely (and to get the best results from your router), the router bits need to be installed properly into the router's collet. Improper installation of your bits can cause excessive chatter and could increase the likelihood that the bits will break when in use. 

Clean and sharp

First of all, before beginning any routing operation, check your bits to make sure that they are clean, relatively free of pitch, and most of all, sharp. If the bit is dull, chipped, is excessively burned or has any other defect, it should be sharpened or replaced before use. 

Correct collet and collet nut fit

Most router collets have a recess (groove) that needs to click into a circlip that resides inside the collet nut. Failing to ensure that the collet 'clicked' into the collet nut will cause you to struggle to remove the router bit after tightening. This could cause the collet to break or be removed by a technical repair centre.

 

Correct fit inside the collet

When installing the bit into the collet, do not tighten the collet with the bit 'seated.' Instead, insert the bit until the shank (bit shaft) reaches the bottom of the collet, then ease it out about 2 mm before tightening the collet.

When the bit is tightened, there should be no less than  2/3 's of the length of the shank in the collet. If your bit has a shank that is too short, then the bit should be replaced. 

 

Safety gear

There are a few other safety measures to keep in mind whenever you use your router. First of all, remember to always wear appropriate safety gear as indicated above.

Correct speed setting

Second, be sure to set your router to the proper speed for your router bit. Setting your router to an incorrect speed will not only affect the router's performance, but also can cause the bit to break much more easily and even cause bodily harm. The speed at which a router bit turns can be important. The typical router runs at about 22,000 rpm, which is fine for most bits. But as the diameter of the bit increases, you ll want to slow things down.

Also, before beginning any routing operation, be certain that you give the router's motor time to come up to full speed for the chosen setting. Beginning to cut before the bit is at full speed can give less than desired results.

Mini Aussie LOVES
Flavor Name: Peanut Butter, Size: Large, Flavor Name: Peanut Butter, Size: Large
My little Meg loves these chew bones, she sneaks in and steals them from our Golden Retriever and our Great Pyrenees. She chews the orange covering off in minutes and the under bone lasts a few weeks. The dogs steal them from each other all the time, even though I buy them each one. Highly recommend if you have a super chewer, just be mindful the orange cover is easily chewed off.

But It
Flavor Name: Peanut Butter, Size: Medium
My fur baby has his fair share of toys, but something about this one he won’t put down. Pieces fall off the ends once they chew on it for a while.

A hardy chew toy
Flavor Name: Peanut Butter, Size: Medium, Flavor Name: Peanut Butter, Size: Medium
My dog loves these! I have purchased several. The size is perfect for my 25-pound cockapoo. It’s durable and she chews them for months until they’re prickly and not as fun anymore. The price is reasonable enough and she loves them so well (they’re one of the two chew toys that she likes), so I feel like the cost is worth it. One thing to note is that my dog does chew off tiny bits from the bone. She usually spits them out but has swallowed some bits here and there. There hasn’t been a situation with the swallowed pieces, but I always monitor her as she uses it and would suggest that for other pet owners also. Safety is always key, but we have never had any problems in the two years I’ve been buying them.
