Drill bit for workshop and DIY use, designed to cut clean, accurate 16mm holes in wood, plastic and soft metals, sourcing map Drill Bit. Quick penetration and reduced tear-out help DIYers and small workshop owners finish projects faster with fewer touch-ups. Is the nitrided 4241 high-speed steel suited to regular metalwork, or best kept to light-duty tasks?
⚡ At a Glance
- • Cutting Quality: Sharp 118° point with 16mm cutting edge for clean, precise holes across wood, plastic and soft metals
- • Best for: DIYers, hobbyists and small workshops needing reliable large-diameter holes in light-duty materials
- • Not ideal for: Heavy-duty industrial machining or drilling thick, hardened steels
16mm cutting edge with a 1/2" reduced shank, 75mm flute length and 150mm overall length. Nitrided 4241 high-speed steel and a 118° standard point suit general-purpose drilling in medium-hardness materials.
Clean, precise holes - with a 118° standard point and sharp cutting edge
The 118° tip angle is the traditional standard for general drilling, allowing the cutting lips to bite quickly and centre without excessive push. A sharp cutting edge and full flute profile remove material effectively as the hole forms.
Fast penetration and reduced tear-out produce neat hole edges in wood and plastics, and help when drilling thin metals for neater finishing and less rework.
Longer wear and corrosion resistance - with 4241 high-speed steel and a nitriding black finish
4241 high-speed steel offers improved toughness for light-duty machining, while the nitriding surface treatment increases surface hardness and resistance to wear and corrosion. The combination balances cost and practical longevity for non-heavy industrial use.
Sustained cutting performance across repeated DIY tasks means fewer replacements and steadier hole quality over time.
Greater workshop compatibility - with a 1/2" reduced shank
A reduced 1/2" shank allows the larger 16mm cutting edge to be used in drills and chucks that accept a 1/2" shank, making the bit suitable for smaller equipment and light-duty machines. The geometry keeps the cutting diameter separate from the chuck size.
Ease of fitting into common small drills expands workshop use without needing heavy-duty machinery, useful for home maintenance and woodworking projects.

❓ Frequently Asked Questions
Q: What materials can the bit drill through?
A: Suitable for plastic, wood and medium-hardness metals such as thin stainless steel, copper, aluminium and iron, as stated in the product description.
Q: How should I start a large 16mm hole?
A: Begin with a smaller pilot hole and keep the drill at a 90-degree angle to the workpiece, which helps accuracy and makes enlarging holes easier.
Q: Is the nitriding finish useful?
A: Yes, the nitriding black finish enhances wear and corrosion resistance, helping the bit last longer during light-duty machining.
🏆 Our Verdict
The sourcing map Drill Bit is ideal for DIYers and small workshops needing reliable 16mm holes in wood, plastic and light metals. A sharp 118° tip combined with nitrided 4241 high-speed steel and a reduced 1/2" shank gives a practical mix of cutting performance and workshop compatibility. The durable finish and straightforward geometry make it a sensible long-term choice for light-duty use and regular home repairs.
