Abrasive Flap Discs
Flap discs blend and finish in one operation which replaces
the traditional two- step grinding process of T27 grinding wheels and sanding discs.
Engineered for full use of the coated abrasive material.
Layering the abrasive cloth flaps allows the discs to wear
evenly which constantly exposes new sharp grain.

Bonding system: CDTooling uses a resin bond developed especially for flap disc applications
which withstands the high temperatures that develop when a flap disc is in action
– on average 16,000 SFPM (surface feet per minute).
This strong bond provides for longer grain retention and leads to better stock removal and longer life
Backing system: The water resistant polyester-cloth (C3, A3, Z-Stainless, Aluminum) or poly-cotton
(Z3, Z-PCE, Z-THRU) backing provides greater strength for grain retention,
low stretch, and is tougher than typical cotton cloths.
CDTooling also offers the cotton backed Z-Flex for applications that require maximum flexibility
Backing Plate: Fiberglass, trimmable.
Multiple Grains: CDToolig offers multiple grain options; the right grain for the work at hand.
Diameters: Available in 2" – 7"
Grits: 24 – 120 Design Type (Shape): Type 27, Type 29 and Compact
4-1/2" Z3 has five disc densities: Regular, Compact, Ultimate, XL, and XXL.
Compact and Ultimate have 20-25% more material than regular. XL and XXL have 35-80% more material than regular.
5/8-11 hub available for 4-1/2" – 7" flap discs. 4" has 3/8-24 available

LABORATORY RESULTS
Flap Disc Performance Comparatives
Flap disc specimens
Disc #1: CDTooling A3 Material 7"x7/8" 40 Grit (A/O material), Type 29, Regular Density
Disc #2: CDTooling Z3 Material 7"x7/8" 40 Grit (A/Z material), Type 29, Regular Density
Disc #3: CDTooling Z-Stainless Material 7"x7/8" 40 Grit (A/Z material), Type 29, Regular Density
Disc #4: Competitor’s Material 7"x7/8" 40 Grit (A/Z material), Type 29, Regular Density
Power tool source
Bosch GWS 20-80, 2KW, 8,500 RPM Right Angle Grinder
Test Parameters
Engagement load of power tool: 11 lbs. vertical force
Rotation and speed of material: Clockwise @ 21 RPM Angle of disc contact: 10 degrees (disc automatically changes its tilt, left to right, 5 times/minute) Measurement criteria: Each disc was tested for six 5-minute grinding cycles, totaling 30 minutes.
After each 5-minute cycle the disc and material was weighed to determine weight loss during cycle.
“G” ratio
The “G” Ratio is the number of grams removed (material) per gram of abrasive cloth (disc) lost during test.
