A versatile step drill bit for metal that creates fast, clean holes across a range of thin materials. Perfect for DIYers who want neat cable entries and enlarged holes with fewer bit changes, the YOKOCUT Step Drill Bit combines HSS 4241 and a titanium coating for durability. Are those claims borne out in use?
⚡ At a Glance
- • Cutting Quality: Two-flute HSS 4241 with titanium coating delivers smooth, burr-reduced holes and steady cutting action
- • Best for: DIY enthusiasts and tradespeople making stepped holes in thin metal (up to 4mm), wood and PVC (up to 5mm)
- • Not ideal for: Hard or brittle materials such as stainless steel, glass, tiles and masonry
High-speed steel core is paired with a titanium coating and a 5–35mm stepped range. A 9.5mm quick-change hex shaft fits most home DIY drill chucks and quick-change holders.
Clean, burr-free holes – with two-flute HSS and titanium coating
Two-flute geometry clears chips more evenly than single-flute steps, while HSS 4241 provides a resilient cutting substrate. A titanium surface layer reduces friction and helps the edge resist wear and heat during repeated cuts.
Cleaner finishes require less deburring and produce neater holes for gland fittings and cable pass-throughs. The reduced heat build-up preserves edge sharpness for longer runs.
Multiple hole sizes with one bit – with 5–35mm stepped design
A stepped profile presents a sequence of increasing diameters in a single conical bit, with pronounced steps that register as tactile and audible stops. The high step design helps control final diameter by giving a clear stop at each increment.
Save time by avoiding bit changes when enlarging holes or creating multiple common diameters. Consistent step stops help prevent accidental oversizing of holes.
Fast, hassle-free use – with 9.5mm quick-change hex shaft and HSS build
A 9.5mm hex shank fits most quick-change chucks and standard drill holders for secure engagement. HSS 4241 construction offers a balance of toughness and cutting ability suited to thin metals and softer materials.
Quick swaps and solid retention speed up jobs around the house or on-site. Real-world feedback notes rapid cutting through mild steel without excessive overheating.
