Types of Blades
Different blades are required for different materials and different sub-straights. Although the choice is situation
dependent, below are describe a few examples of common industry practice:
- Self-scoring blades used to vinyl, carpet tiles, soft to medium PVC, soft cork, linoleum,
enhancer and unibond hot melts. Scoring is made automatically by the “wings” of the blades.
- Heavy duty blades are prepared to work on wood, thin ceramic, tile, VCT, VAT, re-scraping
thin set, glued ceramic, elastomeric coating, or rubber epoxy. After some work period the
blades need to be sharpened.
- Shoe blades/angle shank blades for ceramic, thin set, wood, decorative concrete, mud set.
- Extra heavy duty blades for wood, VCT, VAT, thin ceramic, re-scraping, all carpets,
elastomeric coatings, cork, rubber, and urethane coatings.
- Premium tempered blades for VCT, VAT, rubber tile, cork, all glued carpets, and elastomeric
coatings.
- Razor/scraper blades for thin mil coatings (urethane paint), thin epoxies, poured
elastomeric, and hard to remove adhesive.
- Shoe blades/angle shank blades with carbide tips for wood, ceramic, elastomeric
coatings and epoxy.
Using correct blades is only half of being successful. Second is to put the tool in optimal geometry to the ground.
Listed below is a basic guideline to the most popular angles for specific materials:
- VCT tiles: slide plate with distance between 1/4” to 1/2" from floor. It’s better to start with
narrow cutting head.
- Foam back carpet set-up: slide plate with distance from 1/4” to 1/2” to the floor. Is possible
to use cutting head from 10” to 14”. In some situations however wider blades can be used.
- Ceramic set-up: slide plate from 1/4” to 1/2”. Best working blades are Shank Blade or Shank
Blade with a carbide tip.
- Secondary backing carpet set-up: slide plate with distance from 1/4” to 1/2” to the floor.
Proposed settings are cutting head from 10” to 26” with Heavy Duty Blades or a cutting head
(10” to 14”) with Self Scoring Blade.
- Double stick carpet set-up: slide plate with distance from 1/4” to 1/2” from floor. In this
case it good to start with cutting head (10” to 14”) with Self Scoring Blade. It is important to
have very sharp blades.
- Wood set-up: slide plate with distance from 1/4” to 1/2” to the floor. Preferred are Shank
Blades, Shank Blades with carbide tips or a cutting head (6” to 8”) with Shoe Blades, Bent
Shoe Blades or Heavy Duty Blades. Machine needs to have angle 45
⁰
to the grain of the wood.
