Keyhole or hang slot cutter

Keyhole cutter 9.58mm wide

This bit is so different from the usual 'edge treatment' bits that it deserves highlighting.

It is a highly specialised bit that is used for one purpose only, to cut keyhole slots in picture frames or any object you would like to hang flat against a wall. If you have ever owned one of these bits, you know that it saves a lot of money and a lot of frustration.

 

Keyhole slots can be put in most picture frames. For a heavy frame, use two slots and two hanging screws. The process is quick and reliable, and saves endless wire and hooks, which you never have anyway when you need them.

These bits are single fluted for easier plunging. When you want to hang a shelf, picture frame, clock, or candle sconce on a wall but don't want the mounting screws to show, use an inexpensive keyhole router bit to cut screw slots instead. Then, when you hang the piece, it will appear to 'float' on the wall. And, with keyhole slots you don't need special hardware. Once you've got the tools set up, you can cut multiple slots quickly and easily.

 

This router bit has a 6.35 mm 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.

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

Excellent for my sensitive skin and rosacea
Another excellent product from this brand. I have type 1 rosacea on my cheeks, even when I avoid triggers (like red wine, warm weather, etc.), and very sensitive skin overall. I've been using the cicalfate serum from this brand for the sensitivity, but it didn't help the redness. After two weeks of using this twice daily, I noticed a significant difference. After a month, I had no redness unless I encountered a trigger. Even then, the intensity of the redness seemed less. I tried going without this product for a month when the first bottle ran out, and sadly, the redness started coming back within a cycle of weeks. I've got this on auto-delivery now, along with the cicalfate serum. I never want to be without it!

Best moisturizer for sensitive skin
I have very sensitive skin and have tried many products over the years. This is by far the best daily moisturizer. I don’t wear makeup other than under eye concealer. This keeps my skin looking and feeling great. Not greasy. One bottle lasts about a month. I have probably bought this 10 times in the past year.

Not as good as the antirougeurs cream
I used to use the Antirougeurs cream and loved it but since they no longer make it, I had to switch. I have been using the redness expert cream for a week and it makes my face even redder. I also started to break out. The texture is good but I don’t think it works like the other cream.

Really helps with the redness
Years ago, my dermatologist recommended this line whenever I had a problem with redness. The redness occurs when I spend time outside, even with sunscreen & a hat. When I perspire it irritates my skin & poof, redness. I started using this, once I found it on Amazon, & this really helps to relieve the pain, discomfort & burning sensation. It has a cooling affect on your skin. Until I found this brand I simply suffered until the irritated skin healed. I apply this at night, especially after being outside & sweating & the redness is gone in the morning. I plan to use this until I no longer need it.

Runny
Doesn't flare up my rosacea but does not reduce redness either. Less moisturizing and runnier than Antirougeurs FORT, which appears to be discontinued. Also dislike the bulky packaging. The squeeze tube took up less space in my travel bag.
