NEO tools 13-821 carpenter's pencil

NEO tools 13-821 carpenter's pencil refill leads are black HB graphite inserts supplied in a pack that contains five pieces in a reusable container. Designed for use with the NEO automatic pencil (model 13-810), these leads produce clear, consistent marks on wood, wood-based materials and common construction surfaces. The HB hardness balances darkness and durability for routine carpentry and masonry marking tasks.

Advantages

These black HB leads provide reliable visibility on a variety of materials while retaining sufficient strength to resist frequent breakage during normal use. The compact container stores five replacement leads, keeping them protected and easy to transport to job sites. Compatibility with the NEO automatic pencil ensures simple replacement and consistent writing length.

Suitable for

• Marking and laying out measurements on timber and boards
• Creating reference lines during carpentry and joinery
• Making visible marks on gypsum, plaster and other construction materials
• Use with the NEO automatic pencil for site and workshop tasks

How to use

Open the container to remove a replacement lead and insert it into the barrel of the compatible NEO automatic pencil (model 13-810) according to the pencil's user instructions. Advance the lead as needed for marking; apply moderate pressure to avoid unnecessary breakage. When the lead shortens or breaks, replace it with another piece from the set and store remaining leads in the container to prevent damage.

Usage recommendations

For best results on rough or dusty surfaces, make a test mark to confirm visibility and, if necessary, increase line thickness through slightly heavier strokes. Store the leads in a dry place at ambient temperature and avoid dropping the container to reduce the risk of cracking.
