What's the difference between a V-TapGuide and an STI V-TapGuide?
How do I use a V-TapGuide?
No. We offer two metric drill guides (3–9.5mm and 10–14mm) and one metric tap guide.
We don't advise it; the tap guide is sized for tap diameters, whereas the drill guide is sized for drill bits.
There is a big difference, and you will find that using the tap guide as a drill guide may lead to inaccuracy.
The largest hole size is 14mm. This is part of the Metric V-DrillGuide.
The smallest hole size is 3/64". This is part of the Mini V-DrillGuide.
This is a 90-degree design that runs through the whole guide.
The "V-groove" can be found on the bottom of the guide. It ensures perpendicular alignment on round and cornered material.
The V-TapGuides can accurately guide hand-tapped threads on insides of holes in order to accept a machine screw or bolt. You can also use V-TapGuides to fix damaged internal threads, or to cut new, larger threads.
Whereas the V-TapGuide was designed to guide commonly used ground threaded taps for their called out bolt size, screw thread inserts (STI) V-TapGuides were made to guide oversized ground threaded taps.
Please note that standard taps will not work with the STI V-TapGuides.
Also, while the regular V-TapGuides are offered in either standard (imperial) or metric sizes, the STI V-TapGuides come in either coarse or fine thread sizes.
The V-TapGuides we stock are so easy to use. Simply:
- Put the tap guide on a work surface with the "V-groove" side resting on said surface.
- Thread the tap through the guide and into the predrilled hole.
- Turn the tap clockwise; this will align it perpendicularly using the guide as its base.
- This ensures a straight, accurately tapped hole.
- Every few turns of the tap, you should unscrew the tap counter-clockwise in order to clear the chips.
Tapping by hand is beneficial because resistance can be felt, and this prevents tap breakage.
