1 inch = 25.4 mm. Decimal (inch) rounded to 4 decimal places; ≈ mm is a conversion for size selection only, not a machining tolerance.
| Item | Specification |
|---|---|
| 25-Size Coverage | One case covers pilot, clearance and general-purpose diameters from 1.0 mm to 13.0 mm — less time swapping sets, fewer stock-outs on the job. |
| 135° Split Point | The split point bites on contact instead of skating across the surface: easier starts on tube, round bar and sheet. |
| HSS M2 Material | M2 high-speed steel keeps its edge through the heat of sustained metal drilling — a working-life advantage over carbon-steel sets. |
| Fully Ground · Bright Finish | Fully ground — shank, flutes and point — in HSS-M2 with an uncoated bright finish: true diameter, smooth chip flow, re-sharpenable geometry. |
| Sharpened Edge & Round Shank | Ground cutting lips for a defined cut; round shank for concentric running in standard chucks. |
| 3-Tier Cascading Case | Three stepped holders tilt forward when the lid opens, so all 25 sizes are readable and reachable at a glance. Clear lid, sliding latch, hang tab. |
| Material | Typical Applications |
|---|---|
| Metal | Steel plate / angle iron / aluminium profile drilling, M6–M12 fastener clearance holes, machine assembly and repair |
| Wood | Woodworking pre-drilled holes, hinge and hardware fitting |
| Plastic | PVC/PE fittings, plastic housings, acrylic holes |
Target buyers: hardware wholesalers / private-label tool brand OEM buyers / industrial MRO distributors / auto-repair and installation service providers / DIY retail chains.
M6–M12 fastener clearance holes are typical application examples, not a machining tolerance commitment.
