Mike Z is saying when the bristles get short and damaged. The abrasive is embedded throughout the disk.

Sorry to hear about your issue. Have you contacted [email protected]​ They can help!!

Hello, Do you have a genuine Foredom motor or handpiece? If the problem is that the handpieces will not stay on the sheath then you can gently remove the black spring C clip at the bottom of the handpiece (being careful not to lose the catch ball bearing.) Once you have the spring clip off you can gently squeeze it a little so that the gap is a little tighter. Then replace it and the catch ball. Thank you for reaching out to us! - Team Foredom

The motor brush "connects" the power cord to the commutator on the armature by floating over the commutator. It translates the electric current to the handpiece motor. As the carbon blocks wear on the motor brushes they will need to be replaced once they get shorter than 2mm. They are about 4mm when new. They should be checked once a month if used every day for 8 hours. Thank you for reaching out! - Foredom Team

Thank you for your feedback and for being a dedicated Foredom fan! We appreciate your enthusiasm for our equipment and your keen observation regarding the terminology we use. You are correct that the traditional definition of a lathe refers to a machine used for shaping materials by rotating them while a sharp tool is applied. However, in the context of the dental industry, the term "lathe" has historically been used to describe equipment that performs similar functions, such as grinding and polishing, even though it may not fit the classic woodworking definition. Our use of the term "benchtop lathe" for this particular product is influenced by its versatile applications in various fields, where it is commonly used for grinding and polishing tasks. We hope this clarifies the rationale behind the terminology. Thank you once again for your support and understanding! - Team Foredom

@@ForedomElectricCo Thank you for clarifying Foredom's stance on your terminology. With that said thank you for introducing me to a different context of the word and being used by a different field then I would be used to. I am always interested in learning things new and you definitely taught me one today. I would have never thought that the term "lathe" would be differently in the dental field. Thanks again for clarifying, Keep making awesome equipment, and can't wait in till the 90 degree head hand piece comes out!!

You're welcome! Thank you again for being a fan. Enter your email on the H.29 Right Angle Handpiece page on our site and we will notify you when it comes in! foredom.pulse.ly/1pxozrbt47 -Foredom

@@ForedomElectricCo I have already done so. Now I just have to wait like everyone else!

Don't worry... we are working hard at it!

Gesswein purchases from the same manufacturer we do. However, our engineering department inspects these prior to selling. We also give a two-year warranty and do any repairs herein at our Connecticut factory in the USA. We have a great relationship with Gesswein... it is a fantastic company. - Foredom Team

Thank you!

After you lubricate the shaft and reassemble it with the sheath, hang it down in an unlined trash can without the handpiece and run it at high speed for 20 minutes. Then stop and wipe off any excess grease of the key tip with a paper towel or rag. Always hang up the handpiece or remove it from the shaft after use so warm grease does not migrate into the handpiece. Thank you for reaching out! - Foredom Team

Good morning! The H.20 quick change handpiece can only use a 2.35mm diameter shank bur. 3mm shank is too large. Thank you for reaching out. -Foredom Team

Hello, All Quick change handpieces H.20. H.20D, H.18, H.18D, H.10 and H.10D can only use a 2.35mm shank bur. Thank you so much for reaching out. If you have any more questions, please call 800-272-2885 or email us at: [email protected]​ for help. - Foredom Team

Thank you for asking! You can use the SR motor with the H.30SJ slip joint handpiece as long as the motor has the slip joint shafting. - Foredom Team

The MADCH-1 dust hood -yes- The MAFH25 filter hood -no- Thank you so much for reaching out to us. Please call 800-272-2885 or email us at: [email protected]​ for help. -Team Foredom

There are 3 types of filters for the MAFH25Filter Hood. They each have a different MERV rating. The highest MERV rating is 15. The polyester filter has a rating of 8 MERV which traps larger particulates 70% - 85% 3.0 - 10 microns. It is great for buffing or as a pre-filter in front of one of the other types to extend their life. The second filter is the polyester/charcoal filter with a MERV rating of 13. It catches 90% particulates 3.0 - 10 microns and 75% of particulates 0.3 - 1.0 microns. It is a great filter used alone or with one of the other filters as a pre-filter. The third type of filter is the pleated filter with a MERV rating of 14. It catches 95% particulates 3.0 - 10 microns and 85% of particulates 0.3 - 1.0 microns. Thank you for reaching out to us! Let us know if you have any other questions. Call us at 800-272-2885 or email us at: [email protected]​ for help.

Yes! Thank you for inquiring!

Thanks for reaching out. Shafting gets hot from bending it too tightly or not lubricating it every 50 hours of use. Please do not apply too much grease either. See videos on shaft lubrication on our channel. Have a great day!

We do not have a video yet on replacing the K.1040 collet. We will put it on our video "To Do" list. Thanks so much!

The handpiece attaches to the sheath not the shaft. The proper way to adjust the shaft and sheath is to slide the inner shaft coupling up completely on the motor shaft and tighten the set screw on the shaft flat. Then thread on the motor connector all the way, snugly. Next, insert the key tip end into the plain end of the sheath and slide the sheath up over the shaft. This is after the shaft has been lubricated with our shaft grease MS10006 which is a high-temperature lithium grease. Insert the plain end of the sheath into the motor connector until only 3/4" of the shaft tip extends out the bottom. Tighten the motor connector set screw. The handpiece catch ball and C spring clip snaps on into the grooved end of the sheath. Then run the unit with no handpiece attached at high speed for 15 to 20 minutes with the shafting hanging down so that the grease is redistributed and any excess comes out the bottom. Wipe off the excess grease and attach the handpiece. Always hang the handpiece up or remove it when done so grease does not migrate into the handpiece which will make it run hot.

This is our only size. Thank you for reaching out. If you have any other questions, please contact customer service at 800-272-2885 or email us at: [email protected]​ for help.
