The new Badeco 8LC100 Micro polishing and micro filing handpiece is a reciprocating handpiece for using ceramic files or miniature files to help finish hard to reach areas that could not otherwise be reached with conventional polishing tools. The Badeco 8LC100 will hold tools up to 3.0mm in diameter and has a stroke length of 1.0mm. Use at speeds from 500 rpm up to a maximum of 7000rpm.

Use the Badeco 8LC100 with Ceramic Files or Glardon-Vallorbe Miniature Files or make your own tools by adapting files and felt points.

Parts used for the conversion are made in the USA and are not covered by


The Ceramic Files and the Vallorbe miniature files are held in the Universal Tool Holder by a set screw. One Universal Tool Holder is included with each handpiece. You can purchase extra Universal Tool Holders, part number 134.743-UTH separately.

Badeco also has a special tool holder for holding tools up to 3.2mm diameter. The 3.2mm tool holder uses 2 set screws to hold tools in place. Purchase these separately using part number 134.743-320.

As with all Badeco products, the fit and finish are truly first rate, and everything fits together like an expensive Swiss mechanical timepiece. The Badeco 8LC100 is a lightweight and reliable handpiece and requires no user servicing or oiling and has a 6 month factory warranty against defects in parts and manufacturing for all parts from the duplex spring attachment up.

We recommend that duplex spring equipped  handpieces be used with Low Speed High Torque Foredom flex shaft motors series TX or LX. This will extend the life of the duplex spring.  Hi RPM's can cause duplex spring failures.

Badeco 8LC100 handpieces are imported into the USA by Otto Frei and then converted for "key tip" USA type flex shaft use. Duplex springs, and all parts related to the USA made duplex spring connections, have no warranty. Duplex springs should not be bent beyond 45 degrees during use! Duplex springs can be damaged easily if operated beyond the 45 degree angle or during detaching the handpiece from the end of the flex shaft. Duplex springs can also fail during normal use. If you choose a duplex spring model, you may want to purchase additional inner duplex springs (Single piece part number 134.279 Foredom HP76-Pack of 12 part number 134.280 Foredom HP76B) and learn how to change out and replace the inner duplex spring, the most common part that can fail.

The Badeco 8LC100 is a micro-polishing/micro-filing reciprocating handpiece used for finishing difficult to reach areas such as corners and recesses that present challenges in hand polishing. This handpiece has a 1mm stroke that can be controlled from 500 to 7000 strokes per minute.

The Badeco 8LC100 measures 106mm (4-1/4") (before being attached to the duplex spring or non-duplex spring USA made attachments to use with a flex shaft). It weighs 55 grams and produces practically no sound at all (30 decibels) and is vibration free. No oiling is ever required as the Badeco 8LC100 is meant for trouble free use 8 hours a day 7 days a week.

The Badeco 8LC100 is also available for use with a Badeco Micromotor system.See Badeco 4LC100.
