Product development and insight Dynabrade will expand offering of shrouded models: Dynafine ®, Pencil Grinders and Disc Sanders.
Vacuum Dynafines ➤ Unique Qualities New Vacuum Dynafine® has the ability to source capture fine particles at the work surface eliminating particulates from entering the work environment. New models will allow the operator to attach the tool directly to any portable or central vacuum system. The connection is made by attaching a 1" O.D. vacuum hose cuff onto the supplied port or threading a 1-1/4" hose into the swivel hose cuff (model specific). Vacuum Dynafine® can be used in various applications, the focus will be materials that need to be contained, Hexavalent Chromium, fiberglass, composites and wood. Tools are not recommended for use with ferrous metals unless combined with an explosion proof vacuum system.

Updated technical literature and support materials
Swirl-Free Check List: Equipment Check: Sander: Random orbital sanders are designed as finishing sanders. To achieve the best finish results, use the sander as a “finishing sander”. Do not exert heavy downward force on the sander. Apply enough downward force to keep the back-up pad and abrasive flat on the surface while still allowing the back-up pad to orbit freely over the surface. Remember – let the sander do the work. Match the sander to the work. For heavy and faster cut rate use a sander with a 3/8" diameter orbit. For moderate cut rate use a 3/16" diameter orbit, and for the lightest cut rate, and the finest in finish sanding use a 3/32" diameter orbit. Excellent results can be accomplished by selecting the correct sanding action, the correct grain abrasive, and the correct sequence of abrasive on the selected sander. 3/8" (10 mm) Dia. Orbit For Aggressive Sanding
Example: Heavy/Fast Cut Rate: 3/8" orbit - < 150X. Moderate Cut Rate, Fine Finish: 3/16" orbit - 150X – 220X
3/16" (5 mm) Dia. Orbit For General Sanding
Lighter Cut Rate, Finest Finish: 3/32" orbit - 220X > 3/32" (2.5 mm) Dia. Orbit For Ultra-Fine Sanding
Check the orbit diameter that is being use for the application. In some cases a 3/32" orbit is more preferable than a 3/16" orbit. 90 PSIG (6.2 Bars) is the required operating air supply pressure. Check the air pressure at the sander while it is running. Note: Promote the use of Dynabrade® maximum flow plugs and couplers to ensure proper airflow. Confirm that the tool is running at the rated "Free Speed" RPM. On an average a 10,000 RPM non-vacuum sander will run at 9,500 RPM; a 12,000 RPM non-vacuum sander will run at 11,500 RPM. A vacuum sander normally runs slightly slower. Note: Removing the sanding residue from the work surface with a central or self-generated vacuum sander will improve the finish. It will also help to extend the life of the abrasive. Consider using a vacuum style sander. Inspect the balancer bearing (pad bearing). Remove the back-up pad and rotate the balancer bearing shaft while holding the counterbalance stationary. The balancer shaft should turn freely.
Back-up Pad: Inspect the face of the sanding pad. The pad must be flat and smooth, without any defects. Check if they are using a Dynabrade back-up pad that is “weight-mated” to the sander. Using another pad can make the sander vibrate excessively and lead to an unacceptable finish. Dynabrade orbital pad face run-out is ONLY .002 - .005. Competitors can be up to .015 - .040.
Abrasive: Use a good quality abrasive. Abrasive product that has an additive to help prevent loading of the sanding disc will provide a superior finish than abrasive that has no additive. When sanding particularly sensitive surfaces such as Corian® and other acrylic solid surface it is best to use a film backed abrasive sanding disc. Film backing forces the abrasive to lie flat on the surface. The grain is then presented to the sanding surface in a very uniform manner.

Swirl-Free Check List (Continued): Sanding Techniques:
Always START the sander ON the surface, and STOP the sander OFF the surface.
When sanding keep the sander, and pad FLAT on the surface. Important: Do not exert heavy downward force on the sander. Apply enough downward force to keep the back-up pad and abrasive flat on the surface allowing the back-up pad to orbit freely over the surface. (see Fig.1) For peak performance, avoid tipping the tool/pad when operating. Best results will be achieved when keeping the pad as flat on the work surface as possible
Fig. 1
WRONG
RIGHT
Follow a set pattern when sanding. It is suggested to pass over the surface following a “North, South, East, West” pattern (see Fig.2), overlapping each pass ¼ the diameter of the back-up pad and abrasive. This insures that the previous scratches are removed and that a uniform finish is achieved. Two “patterns” per sanding step are recommended.
End
Fig. 2 Sanding Pattern Start
Frequently inspect abrasive for tears, folds, or build-up. When changing abrasive to proceed to the next sanding step, first inspect the condition of the abrasive that is on the sander. If any defects are noticed in that abrasive, remove it and install another piece of the same grain and sand the work surface again before proceeding on to the next sanding step. Always clear away sanding dust and abrasive debris before progressing to the next sanding step with a finer "grit" abrasive.

Something you'll see in the field
Part/Product Improvement - ECN-3772 Balancer shaft bearing will be protected by v-seal
V-Seal
2-Hand DynaLocke ® will include v-seal and "top hat"
Similar in thinking to the Dynorbital Supreme® and Dynorbital-Spirit® the 2-Hand products will begin to see the inclusion of the balancer shaft bearing v-seal and "Top Hat" seal. The improved seals will help protect the bearings from debris entering the internal components of the bearing. This update has not taken effect yet. Once this is in production the first serial number will be identified and communicated on the appropriate parts pages. (ECN-3772)
Part/Product Improvement - ECN-3776 Durometer increase, better performance
11343 Contact Wheel Increased Rubber Durometer by 40%
The rubber on contact wheel P/N 11343 has increased in durometer to extend durability. The harder durometer wheel aids in producing proper resistance against work surface and longest lasting life of the wheel. P/N 11343 Wheel is optional on contact arm P/N 11300. (ECN-3776)
Part/Product Improvement - ECN-3774 New material, added date code The composite material used in the construction of composite-style couplers has changed. The change will improve current designs and add to their durability. Another upgrade to design is the back side of the housing will now carry a date code, similar to the date coding on the composite Dynaswivel®. (ECN-3774)
