So the choice of anchor matters far more than the bit: a plastic plug meant for masonry simply spins in the hole, while a spring toggle or a metal cavity fixing spreads the load across a wide area behind the board. Load ratings on packets assume 12.5 mm board in good condition and are pull-out figures, not shelf-bracket figures, so anything heavy should reach the stud behind. Cutting into a wall blind is the real hazard: cables run vertically and horizontally from sockets and switches in defined safe zones, and pipes do not always respect them. ## The options, ranked *Ranked best-first for the stated job. The third column is why the others exist.* | Option | Good at | Bad at | | --- | --- | --- | | Standard HSS or brad point bit | Plasterboard is soft; any sharp bit at low speed makes a clean hole. | Nothing, except that hammer mode turns the hole into a crater. | | Self-drilling plasterboard anchor | Needs no pilot hole at all — the anchor is driven straight in with a screwdriver. | Modest load capacity, and it destroys a large area of board if it strips. | | Hole saw or jab saw | The right tool for a downlight or a socket cutout. | Blind cutting risks hitting cables, pipes and joists. | | Finding the stud | A screw into timber or a metal stud carries an order of magnitude more load than any hollow-wall fixing. | Studs are rarely where you want the fixing. | ## Technique that changes the outcome 1. Rotary mode, low speed, light pressure — no hammer 2. Use a detector to check for cables and pipes, and expect cables above and below sockets 3. Match the drill size to the anchor exactly; oversized holes leave the anchor spinning 4. For anything above a few kilograms, find the stud instead ## What goes wrong - Hammer drilling plasterboard - Masonry plugs in hollow board — they pull straight out - Hanging a TV or a heavy shelf on cavity fixings alone > Compiled practical guidance rather than a published standard. Product formulations vary by brand and market, so read the label — and where the work is structural, electrical or gas, the regulations that apply where you are govern rather than anything here. ## Other drill bit questions | For | Use | | --- | --- | | Tile | A spear-point carbide or diamond bit in rotary mode only — hammer action shatters tile, every time. | | Metal | An HSS twist drill, ideally with a 135° split point, run slowly with firm pressure and cutting fluid. | | Concrete | An SDS-plus carbide bit in a rotary hammer — a normal hammer drill will get there eventually and blunt several bits doing it. | | Masonry | A carbide-tipped masonry bit in hammer mode for brick and block; step up to an SDS rotary hammer above about 10 mm. | | Porcelain tile | A diamond core bit, cooled with water, at low speed — carbide spear points do not cut porcelain. | | Stainless steel | A cobalt bit at low speed with heavy constant pressure and cutting fluid — and never let it stop cutting. | | Wood | A brad point bit for clean holes up to about 13 mm; an auger for depth and a Forstner for a flat bottom. | | Glass | A spear-point carbide or a diamond bit, run slowly under water — and toughened glass cannot be drilled at all. | | Plastic | An HSS bit ground to a shallower rake, or a plastic-specific bit, at low speed with a backing board — acrylic especially will crack. | | Hardened steel | Solid carbide in a rigid setup, or soften the spot first — HSS and cobalt cannot cut anything much above 50 HRC. | | Aluminium | A sharp HSS bit at high speed with a wax or paraffin lubricant — the problem is aluminium sticking to the bit, not hardness. | | Large holes in wood | Spade for speed and roughness, auger for depth, Forstner for a clean flat bottom, hole saw for big diameters in thin stock. | ## Common questions ### Which drill bit should I use for plasterboard?
