Marking Tools
Shop marking tools at MGN Builders Merchants for setting out cutting lines, fixing positions and reference points. Choose from carpenters’ pencils, deep hole pencils, permanent markers and chalk marking products, alongside replacement leads and refills. Select the marking type and colour to suit the surface and whether you need temporary or permanent marks.
Marking Tools for Timber and Sheet Materials
Choose marking tools that leave a clear, visible line on the material you are working with. Carpenters’ pencils are a practical choice for marking cuts and fixing positions on timber. Keeping the point sharp helps you control the line width and mark accurately against a ruler or square.
For everyday work on dry wood, OX medium carpenters’ pencils have a graphite core and come with a sharpener. Their flat-sided shape helps stop them rolling off the bench between measurements.
- Surface suitability: check that the lead suits the material and working conditions.
- Line width: keep the point sharp for fine reference marks and accurate cutting lines.
- Visibility: choose a marking colour that stands out against the surface.
Deep Hole Pencils for Fixing Positions
When transferring fixing positions through brackets, fittings or recessed holes, a standard carpenter’s pencil may not reach the surface behind them. A deep hole marking pencil has a narrow shaft and extendable lead to reach these awkward spots.
The Tracer deep hole pencil can mark up to 100mm deep through a 3mm hole, or 145mm through a 6mm hole. Compare these dimensions with the fitting you need to mark through.
- Hole width: check that the opening allows the pencil to reach the marking surface.
- Marking depth: measure the distance through the fitting to the surface behind it.
- Replacement leads: check the specified size and compatibility before buying refills.
Permanent Markers and Chalk for Different Jobs
Your choice of marking out tools also depends on whether the mark needs to remain or be removed later. For detailed reference lines and labelling, the Tracer fine tip permanent marker in black combines a 0.5mm tip with fast-drying ink. Use permanent ink where a lasting mark is acceptable.
Chalk marking products serve different purposes. Chalk powder is used to refill a compatible chalk line reel for snapping straight lines, while a deep hole chalk marker transfers fixing positions through holes.
- Detailed marks and labels: choose a fine tip where you need a narrow, clearly defined line.
- Long straight lines: use chalk powder with a separate, compatible chalk line reel.
- Surfaces that will remain visible: test the marking product in an inconspicuous area first, as ink and coloured chalk may leave lasting stains.
FAQs
Why are carpenters’ pencils flat?
The flat-sided shape helps stop the pencil rolling off a bench or sloping surface. It also provides a broad gripping surface, while the point can be sharpened to suit the line you need.
What is the difference between medium and hard carpenters’ pencils?
The OX medium pencils use HB graphite, while the hard pencils use 2H graphite. HB generally leaves a darker mark with less pressure; 2H produces a lighter mark and generally holds its point longer. Both OX versions are specified by the manufacturer for dry wooden surfaces.
Can I use a permanent marker on surfaces that will remain visible?
Only use permanent ink where a lasting mark is acceptable, as removal may stain or damage the surface. For visible finishes, test your chosen marking product in an inconspicuous area first. Where possible, place reference marks on an area that will be cut away or concealed.
Does chalk line powder wash off?
Not all marking chalk washes off: some formulations are designed to leave permanent lines. Check the product’s stated permanence and surface suitability rather than choosing by colour alone. Test first on surfaces that will remain exposed.
Can I use any replacement lead in a deep hole pencil?
Do not assume that every deep hole pencil takes the same refill. Check the lead diameter, length and manufacturer’s compatibility information for your model. Choose graphite or coloured leads according to the surface and visibility you need.
