Summary
This guide explains where SLTO Lamellar Flap Discs fit in fabrication and MRO workflows, how to choose the right grit and size, what to expect in pricing and logistics for bulk orders, and how our dealer program works. If you buy for a shop floor, a multi-city network, or you want to become a reseller, use the checklists and tables to move from enquiry to dispatch quickly.

Key Takeaways

• SLTO Lamellar Flap Discs are a versatile and efficient alternative to traditional grinding wheels, offering a smoother finish and cooler cut that reduces rework.
• Choosing the right disc involves matching the abrasive grain (Aluminum Oxide for general use, Ceramic for demanding tasks), profile (flat for surfaces, conical for edges), and grit (from 36 for aggressive removal to 120 for fine finishing) to the specific job.
• While a single flap disc may have a higher unit cost, a cost-per-job analysis shows they can be more economical than other wheels due to fewer changeovers and reduced operator time.
• For bulk orders, it’s essential to specify the exact dimensions, grit quantities, and profile type to ensure you receive the correct product and to streamline the procurement process.
• The guide emphasizes the importance of a reliable supplier and offers a program for dealers and resellers, highlighting benefits like consistent stock, technical support, and tiered pricing.

Who is this for

• Fabrication heads, purchase managers, and operations leads
  
• Distributors, tool merchants, and industrial resellers
  
• Workshop owners who want consistent supply and predictable cost per job

1) What is an SLTO Lamellar Flap Disc

An SLTO Lamellar Flap Disc is a layered abrasive wheel made of overlapping coated flaps on a rigid backing. It removes welds, blends surfaces, and prepares metal for painting or further finishing. Compared to a plain grinding wheel, a flap disc cuts cooler, gives more control, and delivers a smoother finish that often reduces a sanding step later.

Typical use cases

• Weld removal and edge preparation
  
• Bead blending and corner cleaning
  
• Mill scale removal and rust cleaning
  
• Surface preparation before primer or powder coating
  
• Stainless steel and mild steel fabrication work

2) Construction that drives performance

While models vary across grit, size, and backing, these are the common build factors that influence life and finish quality.

• Abrasive grain
  
  • Aluminum Oxide: economical, general purpose.
    
  • Zirconia Alumina: higher stock removal, long life under pressure.
    
  • Ceramic: fastest cut and coolest grind for demanding stainless or hardened steels.
    
• Backing options
  
  • Fiberglass backing: high strength with stable running.
    
  • Reinforced plastic or nylon: lighter feel and smooth balance.
    
• Flap density and layout
  Higher flap density extends life and improves finish. Lower density increases aggression and faster removal at the same pressure.
  
• Resin bond system
  Heat resistant resin maintains grain retention at working temperatures and reduces glazing.
  
• Disc profiles
  
  • Flat (Type 27): for flat surfaces and blending.
    
  • Conical (Type 29): for bevels, edges, and contour work at an angle.

3) Sizes, grits, and machine matching

Choose size by grinder type and coverage area. Choose grit by removal rate and finish target.

Common sizes and specs

Diameter	Bore	Profile	Typical Max RPM	Best for
100 mm	16 mm	T27 or T29	15,000	Light fabrication, compact work
115 mm	22.23 mm	T27 or T29	13,300	General shop floor work
125 mm	22.23 mm	T27 or T29	12,200	Most popular for fabrication
180 mm	22.23 mm	T27	8,500	Large surface prep, plates

Grit selection quick guide

Grit	Result	Typical use
3640	Very aggressive	Heavy weld removal, bevels
60	Balanced	General grinding, blend and prep
80	Medium-fine	Deburring, light rust, pre-paint finish
120	Fine	Finishing, smoothing edges before polishing

Tip: run a conical disc at 1530 degrees for fast removal. Run a flat disc at 515 degrees for blending with a controlled finish. Keep within the printed RPM limit of the disc and the grinder.

4) When to pick SLTO vs other wheel types

• Choose SLTO flap discs when you want fewer changeovers, smoother finish from the grinder, and better control on stainless or thin sections.
  
• Choose a grinding wheel only for extreme stock removal on thick sections where finish is not critical.
  
• Choose fiber discs and backing pads when you want the most aggressive cut and can handle extra steps or dust control.

5) Quality signals to check before a bulk order

Use this checklist to standardize supplier evaluation. It shortens trials and protects your shop floor.

• Balanced running with low vibration at operating RPM
  
• Consistent flap overlap and density across batches
  
• Uniform grain distribution that holds cut rate over the life of the disc
  
• Clear markings for diameter, grit, profile, max RPM, and safety icons
  
• Batch traceability and standard packing to avoid transit damage
  
• Availability across core grits from 40 to 120 in your main diameters
  
• Sample verification on your own machines before first bulk

6) Cost-per-job logic that saves budget

A flap disc can look costlier per piece than a basic wheel. Over a shift, the opposite is true when you consider time-on-part and rework.

Simple illustration

• If a 60-grit flap disc lasts for 25 minutes of continuous grinding on a typical weld and reduces a pass of post-grind blending, you cut changeovers and reduce heat marks.
  
• On a 10-weld batch, fewer disc changes and shorter blending can save 2030% operator time.
  
• With fewer scratches, there is less rework at the paint line.
  

You can create your own baseline by logging removal time per weld, number of discs used per shift, and touch-up after inspection. Apply the same method when you compare suppliers.

7) SLTO for stainless and mild steel workflows

• Stainless steel
  Use zirconia or ceramic in 4080 grits. Keep a lighter pressure to avoid heat tint. Move steadily to avoid regrind.
  
• Mild steel
  Aluminum oxide or zirconia works well. Press slightly higher for faster removal. Finish with 80 or 120 for paint-ready surfaces.
  
• Corners and edges
  Use a conical profile. Keep a controlled angle to avoid undercut.
  
• Large plates
  Use 180 mm discs on powerful grinders for coverage, then switch to 125 mm for final blending.

10) Safety and storage practices

• Inspect the disc before mounting. Do not use damaged products.
  
• Use guards, gloves, face shield, and hearing protection.
  
• Follow the max RPM shown on the disc and the grinder.
  
• Mount firmly on a clean flange.
  
• Store in a cool and dry area away from direct sun and oil.
  
• Train operators on grinding angles and pressure to avoid gouging.
  

Safety training reduces scrap and prevents downtime. Add a five-minute check at the start of each shift and you will see the difference in both finish and productivity.

11) Troubleshooting quick table

Symptom	Likely cause	Fix
Disc burns the work	Too much pressure or wrong grit	Drop pressure, move to coarser grit
Poor life	Low flap density or wrong grain	Select higher density or zirconia or ceramic
Visible scratches after paint	Grit too coarse at final pass	Finish with 80 or 120 before painting
Chatter or vibration	Imbalanced disc or worn flanges	Inspect flanges, change disc, check RPM
Slow cut on stainless	Glazed grain	Reduce pressure, dress lightly, step to fresh disc

12) Frequently asked questions

Q1. Which grits should a general fabrication shop stock first
Start with 40, 60, and 80 in your main diameter. Add 120 if you want a finer finish before polishing or paint.

Q2. How many discs per carton
Carton counts vary by size. Share your preferred pack count in the RFQ and we will align packing to your consumption per shift.

Q3. Can I mix grits in one order tier
Yes. Mixed-grit slabs are available so you can restock all fast movers in one go.

Q4. Do you support white label
If you sell under your brand, share a sample of your label and barcode format. We can discuss timelines and minimums.

Q5. What is the usual lead time
For stocked SKUs, dispatch is fast once your PO and payment terms are cleared. For made-to-order specs, share your required date and we will propose a schedule.

Q6. Can I request a trial kit
Yes. For bulk buyers and dealers, we can arrange a grit and size sample set so your operators can test on actual parts.
