Pro Grade Heavy Duty Parallel Setup Blocks 12 Pack Alloy Steel Gauge Kits For Cnc Milling Router Table Saw Precision Machining Tool Shop Ready Gear Bundle

Precision CNC Milling Parallel Jig Block Set
✔️ 12pc Alloy Steel Clamps 0.005mm runout HRC55 wooden case

This 12 pack of setup blocks gives machinists reliable reference surfaces for clamping workpieces flat on rotary tables. The set is pretty handy for CNC mills, desktop routers, and table saw jigs because it delivers repeatable alignment without guesswork.

✅ Six matched pairs ranging from 10 x 47 x 200mm up to 10 x 62 x 200mm for flexible gap filling
✅ Machine ground to a strict 0.005mm parallelism tolerance for tight positional consistency
✅ Heat treated alloy steel core delivering a solid HRC 52 to 58 rating against wear
✅ Arrives organized in a reinforced wooden crate to keep edges sharp and surfaces clean

💡 How do you get accurate alignment when setting up jigs on a CNC mill?
Reliable reference geometry saves serious shop time when holding uneven blanks. Look for these features:
- Cold forged alloy steel that resists deflection under cutting loads
- Precision lapped edges that lock onto vises or fixture bases without slop
- Standardized cross sections that stack quick for custom height adjustments
- Consistent heat treatment levels that maintain square faces through repeated tool changes
