Corner Round Router bit


Carbide Tipped

The corner-rounding bit rounds an edge to a given radius. The tool is shouldered to cut a fillet if required. The cut can be used to ease edges, as a simple profile, or as a part of a complex one. Other names for this router bit are round-over, rounding over and quarter-round. If a smaller pilot bearing is used, a second shoulder can be produced, in effect making the bit a beading bit.

Rounded edges give a project a softer, smoother look. The greater the radius of the round-over, the more pronounced this effect becomes.

Rounding an edge makes it more durable because it won't show dents, splinter, or lose its finish as easily as a sharp corner. Like a knife that loses its sharp edge, a rounded corner is more 'friendly' to people or objects that come in contact with it.

Manufacturers classify round-over bits according to the radius they cut. So, a 3/8 inch round-over bit cuts a 3/8 inch radius, and so forth. To determine the radius of a round-over bit, measure either of the dimensions shown in the drawing.

This router bit has a 6,35 mm shank (shaft) that will fit most small or large 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.

General safety suggestions:

It is advisable to always have the following items nearby and in a good condition

  • Eye protection clean and scratch free
  • Hearing protection quality earmuffs
  • Dust masks discard old and dirty masks
  • Gloves for easy handling of material and hand protection
Wear Gloves

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. 

Observe the following at all times

  • Wear a protective face shield or Safety Glasses to prevent eye and face injury.
  • Wear ear plugs or ear muffs to protect your hearing.
  • Use a respirator or dust mask to give protection from dust particles. Wood dust may remain in the air for hours after using power tools.
  • Always read and follow router operator's manual instructions.
  • Make sure that router rpm's and the bit selected match.
  • Dress properly. Wear short sleeves, no loose fitting clothes, proper footwear and no jewellery. Tie back long hair.
  • Always be sure the router is unplugged before replacing bits and that the switch is off before connecting the router.
  • Be sure the router bit has completing stopped spinning before sitting the router down.
  • Be sure bits, clamps and attachments are secure before starting up.
  • Keep children, pets and visitors at a safe distance.
  • Be especially cautious when working small pieces.
  • Keep hands and fingers away from revolving bits and cutters.
  • Do not operate routers in moist or wet areas.
  • Always grip tool tightly and be prepared at start-up to resist the motor torque.
  • When using a router table, make sure on/off switch is easily accessible.
  • Learn the sound of your router and shut it off at any unfamiliar sounds or irregularities.
    Never start the router with the bit in contact with the material.
  • Always feed in the proper direction, against the direction of bit rotation.
  • Maintain equipment. Replace worn parts, discard worn-out bits and check router periodically. Clean parts with appropriate solvents.
  • Don't operate a tool if you are tired or under the influence of medication, drugs, alcohol or while smoking.
  • Check wood for nails, screws or loose knots before routing.
  • Keep your mind on your work, avoid distractions, work at a comfortable pace and stop before you get tired.

Do a dry run

  • Place the router on the final work surface and test you cut by moving the router over the whole are to cut with THE ROUTER SWITCHED OFF
  • You do not want to waste an expensive piece of wood
  • You do not want to start all over
  • Never met anyone with spare fingers - SAFETY

Will buy again but softer ball preferred
At first Labradors weren’t into it, but I played with them positively reinforcing all touches and now my service dog LOVES the bigger one! It’s perfect between appointments to give her exercise. Will be looking for the same but with a softer ball. It’s a little too heavy and tough if it were to accidentally bounce off a body part besides their mouth catching it.

My dog LOVES this tiny tug ball
Size: Medium(6")
A lot smaller than I was expecting.. BUT my dog doesn’t mind at all. She seriously loves this thing. It goes flat fairly quickly, but that’s what happens with all of her soccer balls, no matter the size. She’s a pitbul catahoula mix and has a strong bite. Considering my dogs chewing abilities, I’m fairly impressed by the durability of the ball, though she chewed through all but one of the rope handles in about 2 seconds. All that said, it’s one of her favorite toys(she’s 13 years old)

My dog loves this. I've had to buy two because my dog destroyed the first one but there's only so much you can do with a 5 month old german shepard.
