Heatset Insert Tool Guide by LDO

LDO’s brass M3 heatset insert tool makes insert installation cleaner and easier. It replaces a compatible soldering-iron tip so you can press M3 heat-set inserts into printed parts with better alignment and heat transfer than a bare iron tip.

Why use the LDO insert tool

• Purpose-built for M3 inserts: LDO documents this tool for M3 brass inserts used in printed parts.
• Adjustable depth setup: the threaded tongue can be set to roughly match insert height, helping keep heat on the insert instead of the printed part.
• Common soldering-iron fit: LDO specifies compatibility with typical sleeved irons using 900M-T-style tips, including many Hakko FX888D-style Chinese soldering irons.

Specifications

• Brand: LDO Motors
• Use: installing M3 brass heat-set inserts in 3D-printed plastic parts
• Tool style: brass heatset insert soldering-iron tip / insert guide
• Soldering-iron compatibility: 900M-T-style sleeved tips per LDO documentation

Pairs well with

• Black Nickel Coated Threaded Heat Set Inserts for M3 insert stock.
• Digital Smart Electric Soldering Iron if you need a temperature-controlled iron.
• Stealth Press Zero or Iconic Fab Stealth Press Complete Kit for a more controlled heat-set workflow.

Gotchas

• This is for M3 inserts; it is not a universal insert-size kit.
• It is not a soldering iron and does not replace temperature control or careful setup.
• Check your iron before ordering: LDO calls out 900M-T-style sleeved tip compatibility, not TS100-style cartridge tips.
