Step drill bit set for making progressive, clean holes in thin sheet materials. The flintronic Step Drill Set gives DIYers three HSS, titanium-coated bits with a 1/4" hex shank for straightforward drilling. Is the range and durability right for home repairs and small workshop jobs?
⚡ At a Glance
- • Cutting Quality: Clean, progressive steps produce controlled hole sizes and smooth edges on thin metals and plastics
- • Best for: DIYers, electricians and small workshop users working with thin sheet materials
- • Not ideal for: Hard or brittle materials such as stainless steel, glass, tile and thick masonry
Three HSS step bits are titanium-coated and fitted with a 1/4" hex shank for use in home drills. Two-flute, high-step geometry helps produce smoother cuts and gives a tactile stop at each diameter.
Progressive hole sizing - with three stepped bits covering 4–32mm
Each bit contains multiple steps: 4–12mm (5 steps), 4–20mm (9 steps) and 4–32mm (15 steps), allowing holes to be enlarged incrementally without switching tools.
Quickly reach a range of hole diameters for different tasks, useful when cutting cable entries, mounting holes or enlarging pilot holes in thin materials.
Longer cutting life - with HSS core and titanium coating
High-speed steel provides toughness while a titanium coating reduces friction and resists wear during repeated drilling operations.
Maintains edge retention better than plain steel bits, so fewer replacements are needed for routine DIY and workshop use.
Controlled, predictable drilling - with two-flute design and high-step profile
Two flutes clear chips more smoothly and the high-step profile gives a tactile stop at each diameter, helping the operator recognise when a step is reached.
Prevents accidental over‑drilling and delivers steady, repeatable holes in thin metal, plastic and wood.
✨ The 4 Key Reasons for flintronic Step Drill Set
- 3-Piece Range - Covers 4–32mm so common small to medium holes need no extra bits
- 1/4" Hex Shank - Suitable for home DIY power drills with compatible 1/4" hex holders
- Titanium Coating - Reduces friction and keeps cutting edges sharper over repeated use
- Two-Flute, High-Step Design - Smoother cuts with tactile stops to avoid oversize holes

❓ Frequently Asked Questions
Q: Are these suitable for stainless steel?
A: No. Product descriptions explicitly state the bits are not suitable for stainless steel, glass, tile or other hard and brittle materials.
Q: What hole sizes are included across the set?
A: The set contains three bits with step ranges: 4–12mm (5 steps: 4, 6, 8, 10, 12), 4–20mm (9 steps up to 20mm) and 4–32mm (15 steps up to 32mm).
Q: Will these fit my home drill?
A: Yes. A 1/4" hex shaft is specified and is suitable for home DIY power drills that accept a 1/4" hex drive.
