Overview

2-pin arrow 1-segment metal bond diamond grinding shoe for WerkMaster concrete floor grinders. The arrow-shape segment concentrates cutting pressure for faster, more directional grinding during concrete surface preparation.

Use this tool during the metal grinding stage after coating removal or when the concrete surface is ready for slab opening, scratch removal, leveling, or prep grinding. Choose the grit and bond according to concrete hardness, current floor condition, cutting speed, and target scratch pattern.

Best For

• Concrete surface preparation
• Faster stock removal on hard or dense slabs
• Scratch removal after aggressive prep steps
• Slab opening before finer grinding
• WerkMaster 2-pin quick-change grinding workflows

Features

• Arrow-shape 1-segment design for aggressive focused cutting
• 2-pin quick-change style for WerkMaster-compatible holders
• Metal bond diamond segment for concrete grinding
• Available grit and bond options for different floor conditions
• Suitable for metal grinding before hybrid or resin polishing stages

Available Grits

6 / 16 / 30 / 60 / 120

Use lower grits for stronger cutting, opening, and heavier scratch removal. Use higher grits when the floor needs better scratch control before transition or polishing.

Available Bond Types

Soft Bond – for hard concrete
Medium Bond – for general concrete
Hard Bond – for soft or abrasive concrete

If the concrete hardness is unclear, test a small area first or send the jobsite details before ordering.

Fitment Note

This product is for WerkMaster concrete floor grinders using compatible 2-pin quick-change holders. Fitment should be confirmed before ordering.

Before ordering, confirm:

• WerkMaster grinder model
• 2-pin holder or plate style
• Required grit and bond
• Quantity needed for the full machine set
• Current floor condition
• Target grinding or polishing result

If the holder or plate interface is unclear, check adapters and plates or send machine and plate photos through Contact Us.

Polishing Workflow

If the floor still has epoxy, glue, paint, mastic, or coating residue, start with PCD coating removal tools before using metal bond grinding tools.

After metal grinding, use hybrid pads if visible metal scratches need refinement before final polishing.

For the final polishing stage, continue with resin polishing pads after the scratch pattern is controlled.

Shipping

Order processing and delivery time depend on stock status, order quantity, destination country, and shipping method. If you have a deadline, send the required delivery date before ordering.

FAQ

Q1: Arrow segment vs. triangle segment — what is the difference?
Arrow segments give a more directional cutting action and are useful when the job needs faster bite during concrete prep grinding. Triangle segments are also aggressive, but the scratch pattern and cutting feel can differ by slab condition and machine weight.

Q2: Which grit should I choose?
Choose 6 or 16 grit for aggressive opening and heavier prep. Choose 30 or 60 grit for general grinding and scratch control. Choose 120 grit when the floor needs finer scratch refinement before transition or polishing.

Q3: Which bond should I choose?
Choose Soft Bond for hard concrete, Medium Bond for general concrete, and Hard Bond for soft or abrasive concrete.

Q4: Is this tool for coating removal?
No. If the floor still has epoxy, glue, paint, mastic, or coating residue, use PCD coating removal tools first.

Q5: What should I use after this tool?
After metal grinding, use hybrid pads to refine scratches, then continue with resin polishing pads for polishing.

Q6: What should I send before ordering?
Send your WerkMaster grinder model, holder or plate photo, required grit, bond preference, current floor condition, target finish, and quantity.
