A step drill bit is designed for progressive hole sizes and cleaner finishes when drilling metal and softer materials. DIYers and tradespeople who need tidy, repeatable hole enlargements will appreciate the YOKOCUT Step Drill Bit. Will the HSS 4241 core and titanium coating stand up to regular workshop use?
⚡ At a Glance
- • Cutting Quality: Sharp HSS cutting edges with two-flute geometry for smoother cuts and fewer burrs
- • Best for: DIY enthusiasts and tradespeople needing progressive hole sizes in soft metals and plastics
- • Not ideal for: Hard or brittle materials such as stainless steel, glass, ceramic tiles or masonry
Made from HSS 4241 with a titanium coating and two-flute design for stepped holes from 4mm to 22mm. The 8mm tri-flat hex shaft fits most home drills and battery-powered drivers.
Precise hole control – with high step design and two-flute geometry
High step geometry provides distinct mechanical stops between diameters while the two-flute profile clears swarf quickly for a smoother cut. Sharp HSS edges maintain clean edges through each step.
Feelable steps prevent accidental oversizing, producing neater holes for grommets, cable entry or fitting fasteners without constant bit changes.
Longer edge life – thanks to HSS 4241 and titanium coating
HSS 4241 offers toughness and resistance to deformation when cutting metals, while the titanium coating reduces friction and helps dissipate heat. Less heat means slower wear on cutting edges.
Reduced wear keeps cutting performance consistent over multiple uses, so fewer replacements are needed during regular workshop or home tasks.
Hassle-free fitment – with 8mm tri-flat hex shank
The tri-flat shank geometry prevents slipping in chucks and quick-change holders and is sized to sit securely in most 8mm chucks and adaptors. Geometry also suits battery-powered screwdrivers.
Secure grip and quick changes speed up jobs, making it straightforward to use with cordless drills and screwdrivers on-site or at home.
