The Foredom H.20D Handpiece is identical to the H.20, but it has a duplex spring for added flexibility. Ideal when more precise control is required for delicate work. Use with 2.35mm (3/32”) shank burs and accessories.
A simple twist of a level on the side lets you change accessories with ease. The ergonomic design makes it comfortable to handle while working.
Duplex springs are subject to breakage and are NOT covered by warranty. They are made of special steel, double wound tubular construction with a protective flexible spring cover. Replacement springs (HP76) are available and can be installed by the user. We recommend that only experienced users of flex shaft tools consider purchasing this style handpiece. For most users, the "straight" handpiece (106-H20) is the preferred solution.
To avoid breakages or damage to springs, do not bend the spring at sharp angles of more than 45o.
Do not exert excessive pressure onto your work, but let the speed of the tool do the work for you.
Do not use the Duplex spring adapter with large buffs more than 1” in diameter, aggressive burrs, or chisel handpieces.
If the bur shank does not feel secure once set in hand piece, you need to adjust the collet. Never leave collet closed without a bit as this will damage the spring holding it tightly closed.
The H.20D is a member of the Foredom system of interchangeable handpieces.
