Drill Bit Guide: Choosing the Right Bit for Your UK DIY Projects

Whether you’re putting up a new shelf in a Victorian terrace, installing kitchen cabinetry, or working on a weekend woodworking project, the success of your task often boils down to one small piece of engineered metal: the drill bit.

Using the wrong bit isn't just frustrating; it can damage your expensive power tools, ruin your workpiece, or even lead to injury. This guide from SGS Engineering breaks down exactly which drill bit you need for the most common household and trade materials.

1. Drilling into Wood (The All-Rounders)

Wood is the most common material for DIY, but not all wood bits are created equal.

• Twist Drill Bits: These are the standard bits you’ll find in almost every kit. While versatile, they are best suited for general timber and plastic.
• Brad Point (Lip and Spur) Bits: These are a woodworker's best friend. They feature a sharp central point that stops the bit from "wandering" across the wood surface, ensuring a perfectly centred hole.
• Flat Bits (Spade Bits): Need to run a cable or a pipe through a joist? Flat bits are designed for boring large-diameter holes quickly.
• Forstner Bits: If you’re installing concealed kitchen cabinet hinges, you’ll need a Forstner bit. They create clean, flat-bottomed holes that don’t go all the way through the timber.

2. Drilling into Masonry and Brick

UK homes are famous for their solid brick and blockwork. If you’re mounting a TV or a heavy mirror, you need a bit that can handle the grit.

• Masonry Bits: These are easily identified by their "winged" carbide tips. They are designed to be used with a hammer drill (or SDS drill). The hammering action shatters the masonry while the bit clears the dust.
• SDS Bits: If you have a heavy-duty SDS drill, you must use SDS-compatible bits. These have a unique shank that slots into the chuck to provide more power for drilling into reinforced concrete or hard engineering bricks.

3. Drilling into Metal

Precision is key when working with metal.

• HSS (High-Speed Steel) Bits: The standard for drilling through soft metals like aluminium or mild steel.
• Cobalt Bits: If you are tackling stainless steel or other hardened metals, standard HSS will likely blunt instantly. Cobalt bits are more heat-resistant and durable, making them the professional choice for tough alloys.
• Step Bits (Unibits): Perfect for sheet metal work, these cone-shaped bits allow you to drill multiple hole sizes without changing bits.

4. Specialised Jobs: Tiles and Glass

Nothing strikes fear into a DIYer like drilling into a brand-new bathroom tile.

• Tile and Glass Bits: These feature a spear-shaped tungsten carbide tip. The trick here is to go slow, use a constant light pressure, and never use the hammer setting, or you’ll crack the tile instantly.
• Diamond Core Bits: For very hard porcelain or stone tiles, a diamond-tipped bit is often necessary to get a clean finish without heat damage.

Elevate Your Toolkit: Why Professionals Choose Rikä

When you’re midway through a demanding install or tackling a precision woodworking project, the last thing you want to worry about is your accessories failing. That’s where Rikä comes in.

Available at SGS Engineering, Rikä has rapidly become a go-to brand for UK tradespeople and serious DIY enthusiasts who refuse to compromise on quality. Rikä bridges the gap between "hobbyist" gear and overpriced "premium" labels, offering professional-grade durability at a price point that makes sense.

Why Rikä Stands Out in the Workshop

Rikä isn't just about making bits; it’s about making bits that last. Here is why they are a staple in toolboxes across the country:

• Superior Metallurgy: Rikä bits are engineered using high-grade materials like M35 Cobalt and Tungsten Carbide, ensuring they stay sharper for longer, even when drilling through toughened stainless steel or dense masonry.
• Precision Engineering: Every Rikä accessory is manufactured to exacting tolerances. This means less "wobble" (runout) in your drill, leading to cleaner holes and less strain on your power tool's motor.
• Tailored for the UK Market: From SDS+ bits designed for tough British engineering bricks to specialist porcelain tile bits, Rikä understands the specific materials we work with in the UK.
• Extensive Range: Whether you need a single replacement bit or a comprehensive 100-piece professional set, Rikä offers a solution for every application—wood, metal, masonry, and more.

Pro Tip: If you're starting a large-scale renovation, look at the Rikä Professional Accessory Sets. They offer the best value for money and ensure you always have the right gauge on hand when you hit an unexpected material.
