Raptor Supplies offers a complete line of thread insert tools from Chrislynn, Helicoil, Recoil and Grainger. We also offer a wide range of insert installation tools, STI plug taps, tang breaking tools and bushings for installing threaded inserts into a pre-drilled hole. Steel power drivers in different hex shank sizes are also available for installing self-locking or knife thread inserts.
Features
These tools feature threading on the external surface to create a secure connection with the inserts and handle, for easy manoeuvring inside the drilled hole.
Screw thread insert (STI) plug taps are tapping tools used to create a threaded hole with an oversized internal thread for accommodating a helical screw insert.
Buying Guide
Based on Thread Direction
Left Hand
Thread rises from the bottom right to top left when viewed from the front.
Can be tightened by turning to the left. Once fastened, they resist loosening from counterclockwise motion.
Right Hand
Thread flanks rise from bottom left to top right.
Allow the user to apply greater torque when turning the lead screw clockwise than against it.
Types of Helical Thread Insert Tools
Installation Tools for Helical Inserts With & Without Prongs
Screw an insert into these tools and drive them a quarter to half turn below the surface of the material.
Prong Break-Off Tools for Helical Inserts
Drive the tip of these tools into the installed inserts and push down to activate the spring-loaded punch, which will break off the prong.
Extraction Tools for Helical Inserts With & Without Prongs
Drive the tip of these tools into an insert and strike the tool's head lightly. Use pressure to turn the tools counterclockwise to extract the insert.
Types of Threaded Insert Tools
Pull-to-Pressure Tools
With most threaded insert tools, the bulge on the blind side is set using a preset distance. These tools set the insert using a preset pressure, which won't crack the material. They are commonly used with thin metals or hard plastics.
Spin-Spin Tools
They are used to secure a threaded insert. The threaded insert is screwed into a pre-drilled hole after being fitted to the mandrel. As the mandrel spins, it draws the threaded shank from the material's blind side, forming a solid connection that will not turn inside the hole. Once installed, the tool spins in the opposite direction to complete it.
Spin Pull-Off Tools
They function similarly to spin-spin tools, such that the threaded insert is fitted to the mandrel before being inserted into a pre-drilled hole. To install the insert, the tool screws the insert into place and once set, the tool applies pressure to the blind side to create a bulge on the blind side.
Prewinders
They are used to install tanged inserts for production runs, as well as prototype, salvage & repair work.
Frequently Asked Questions
How to install helical inserts?
Drill a hole using the suggested drill bit size.
Tap the hole, then screw the insert into the installation tool. The prong must be properly engaged in the driving contour of the tool.
Using the installation tool, thread the insert into the hole. Install the insert a quarter to half turn below the hole's surface.
If your insert has a prong, remove it with a punch or break-off tool. Remove the prong to allow your screw to fully enter the insert.
Why break the tang on a Helicoil?
If the tang is not properly removed, the hole might get compromised and the male fastener will not be able to pass through. Browse through our catalogue to find the right tang break-off tool for your needs.
What is the use of a mandrel?
A mandrel is a piece of metal that is used to support a partially machined workpiece while it is being finished, or as a core around which parts can be bent / forged / moulded.
