Introduction

AMSUO — PROFESSIONAL DRILLING SOLUTIONS

HSS M2 Twist Drill Bit Set · 25 PCS

PRECISE · DURABLE · WIDE APPLICATION

HSS-M2 Fully Ground | 135° Split Point | Bright Finish

25 PCS · 1.0–13.0 mm (DIN) / 1/8"–1/2" (ANSI) · 3-Tier Tough Case

Key Selling Points

25 sizes, no gaps — Metric (DIN) 1.0–13.0 mm in 0.5 mm steps; imperial (ANSI) 1/8"–1/2" in 1/64" steps: the sizes most jobs actually call for, in one case.
Big sizes included — The set reaches 13.0 mm (1/2"), covering close-fit clearance work around M12 fasteners and heavier sheet-metal jobs that smaller sets stop short of.
HSS M2 high-speed steel — M2 grade resists the heat of continuous metal drilling better than carbon steel, keeping the cutting edge alive.
135° split point — Self-centering tip reduces walking on smooth or curved surfaces and cuts the push force needed to start a hole.
Fully ground, bright finish — Shank, flutes and point fully ground in HSS-M2 with an uncoated bright finish: true diameter, smooth chip flow, re-sharpenable on site; round shank runs concentric in standard 3-jaw chucks.
3-tier tough case — Clear-lid hard case with a cascading three-tier holder: sizes stay legible and every bit is reachable without emptying the box. Sliding latch and hang tab included.

Features Explained

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.

Materials & Applications

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.
