Test for a secure hold by pulling on the accessory. To release the accessory,
slide latch out again and pull out accessory.
Quick Change Type
Nos. 7A and 7AD Handpieces:
These handpieces have a push-pull collet closer. Pull the handpiece grip back
as far as it will go. Insert accessory shank (size 2.35mm only) as far as it will go.
Push front portion of the handpiece forward firmly. Test for a secure hold by
pulling on the accessory. To release accessory, pull handpiece grip back with
firm pull. Pull out accessory.
Nos. 10 and 10D Handpieces:
These handpieces operate only when a 2.35mm shank bur is inserted. It will
lock if bur is not inserted. To insert bur, move lever 180º clockwise towards the
back (shaft connection end) of handpiece. Insert or change a 2.35mm shank bur
and move lever 180º forward. Make sure lever is completely locked into the
forward position.
Nos. 18 and 18D Handpieces:
These handpieces have a lever on side of handpiece. Push the spring loaded
lever in to open collet and release the shank of accessory (2.35mm only). Insert
accessory while holding the lever down with thumb or finger. Never push lever
down while handpiece or flexible shaft are rotating.
Nos. 52, 52D, and 53 Handpieces:
These quick change handpieces have a unique push/pull collet chuck release
mechanism for rapid accessory changing (2.35mm only). Wait for the motor, flex-
ible shaft, and accessory to come to a full stop before opening the chuck. After
accessory has stopped rotating, pull the outer grip forward with one hand while
holding the back of the handpiece with the other. Remove the accessory and
insert the shank of the new one at least 1
″ (25mm) into the chuck. Pull the grip
all the way back until the chuck snaps closed.
Be sure to read the following accessory recommendations before using
your Foredom Power Tool.
General Accessory Recommendations
The wide assortment of Foredom accessories makes your flexible shaft power
tool very versatile. Grinding, sanding, brushing, cutting, buffing and polishing can
all be easily accomplished. Choose the right accessory for your special needs
by referring to the Foredom Accessory Catalog No. 350. Accessories may be
purchased through your local dealer or by contacting: The Foredom Electric
Company, 16 Stony Hill Road, Bethel, CT 06801, (203)792-8622.
Always let the speed of the power tool do the work. Avoid forcing the tool or
applying too much pressure. Experience will help you choose the right speed for
the work you are doing. It's always a good idea to practice on a scrap piece of
the same material you plan to work on to determine the best accessories and
speeds to use.
Always follow the manufacturer’s RPM or speed recommendations when
selecting accessories.
Your Series K motor is supplied with a variable speed control so that you can
operate it at the most suitable speed for each job. The motor has a maximum
speed rating of 18,000 RPM. Always use an accessory which has the same
or a higher rating than your tool. Using an accessory with a lesser rating
can result in serious injury.
1. Abrasive Points, Wheels and Discs:
Use Silicon Carbide (green color) for low-tensile, brittle or “smeary” types of
metals such as aluminum or brass. Use Aluminum Oxide (red color) for fast
cutting on high-tensile, tough materials such as steel and malleable iron. Also
use on glass and porcelain, etc. Aluminum Oxide (white color) points have an
extremely fine grit for producing a fine, high finish on high-tensile materials
including gem stones, stainless steel, and glass. Rubber Bonded Abrasive
Wheels are used for removing rust and for polishing with various grits. For best
results, use finer grits for finishing at high speeds and coarser grits for stock
removal at lower speeds. New CeramCut Blue
TM Stones are made from a mixture
of special man-made ceramic grain and aluminum oxide bonded together. The
ceramic grain provides a faster cutting action and is more durable so that shapes
are maintained longer than pure aluminum oxide stones.
2. Burs and Cutters:
Vanadium Steel Cutters are suitable for all materials except hardened steel and
glass. Use Carbide Burs on such materials as wood, plastic and tough alloys
(Carbide is generally referred to as the “hardest man-made metal”). Engraving
Burs are used for fine detailed work on metal and other hard materials. Generally,
use medium speeds for stock removal. Higher speeds are required for finishing
work and for the smaller points. Typhoon
TM Carbide Burs are specifically made for
use on soft and hard woods and plastics.
3. Sanding Drums, Bands and Discs:
These accessories are used for removing rust, smoothing rough surfaces and for
sanding jobs on wood, plastic and metal. (Avoid using too much pressure which
will cause clogging or a build-up on the work surface.) For best results, use medi-
um speeds for coarser grits and larger diameters. Use higher speeds for
finishing work or with smaller sizes.
4. Cotton or Felt Bobs and Buffs:
Solid Felt Buffs or Bobs are used in combination with gritty or smooth compounds
for a variety of buffing and polishing operations on plastic, wood, and metal. They
vary in shape and come in three hardnesses — medium, hard, and rock hard.
Loosely-stitched Soft Cotton Buffs are used for delicate work; especially work
with precious metal and during polishing operations. Generally, use high speeds
for cutting down and buffing. Medium speeds are used for delicate, precise work
and for polishing.
5. Brushes:
Miniature power brushes are generally used on metal surfaces and hard-to-reach
areas. They are ideal for deburring, surface finishing, edge blending, roughening
to create a good bonding surface, and general cleaning. Use high speeds for
cleaning and deburring. Medium speeds are needed when cleaning hard-to-reach
areas and edge blending.
6. Diamond Burs:
Diamond Burs are used to remove stock from extremely hard materials such as
tungsten and tantalum carbide cutting tools, dies and molds, broaches, and for
lapping and polishing synthetic jewels and precious metals, fiberglass and
reinforced plastics, PVC and ceramics.
