3-9.5MM METRIC V-DRILLGUIDE - MDG100DGNP

I have the full range of these drill guides, including the large and small fractional sizes, the wire gauge size and this one for metric sizes. They are just good tools. The V groove on the bottom is accurately centered on the holes, the tick marks on the side accurately indicate the centers of the corresponding holes, and the holes are perfectly sized for the drills they are designed for. I use them whenever I need to drill a hole accurately with a hand held machine, or to drill a hole into the edge of an existing hole, which is almost impossible without a drilling guide. I have used them with end mills and reamers to enlarge holes, and even with a drill press to keep a drill bit from flexing. They are also good for use with long drills where there is room to clamp the guide, but not enough room for the drilling machine close into the drilling site.

Used this to guide my bit to drill out a bolt in the valve cover of my car. Without this I would've made a mess for sure. I am confident that the HSS drill bit wouldn't affect the hardened steel this is made out of. Great quality.

I recently purchased the Big Gator Tools MDG1000NP V-Drill Guide, and I couldn’t be more impressed. The build quality is outstanding—precision-machined, solid, and clearly engineered with meticulous attention to detail. It requires no installation, and it performed flawlessly straight out of the box. The guide provides a stable, reliable drilling surface, and the V-groove design makes it incredibly easy to drill perfectly straight holes on flat, round, or uneven materials. Every hole I drilled came out clean, centered, and accurately aligned. It’s compact, heavy-duty, and stays firmly in place during use. For the price, the performance and durability exceeded my expectations. I’d highly recommend this drill guide to anyone looking to improve drilling accuracy and consistency in their woodworking or metalworking projects.

String & Heavy, easy to use, alredy used it for drilling floating shelves. I recommend it.

For men who already have everything. For 3-4 years I haven't used once, but when I need it, I have it.

Held my drill bit perfectly straight while I started the hole. I needed to use it on a small flat surface too small for a full sized drill guide.

They aren't an every day use item for me but man when I do, it really saves the day. Today's success story involves either drilling an 1/8" hole in a 1" bolt or waiting 3 or more weeks for a new OEM part to arrive. Great product Useable on flat, square or round surfaces. Helps keep drill straight. Buy one, you won't regret it.

This drill and tap guide is well made and easy to use. I used a spring-loaded center punch to mark my hole in an aluminum tube. Then I inserted my drill bit through this guide and located the hole with the drillbit. Then I placed the guide on the aluminum pipe and clamped them together. I got the holes nearly perfectly perpendicular and cleanly cut.

Je cherchais un moyen pour percer droit er j ai testé plusieurs systèmes plus ou moins encombrant et pas toujours efficace. Le Big gator est une solution que je recomande volontiers. Testé sur la mise en place de lambris, le système est simple et permet de percer correctement à la perpendiculaire. Ça ne vaut pas un tour de perçage mais c est pratique et transportable. L outil tient bien dans la main et le foret engagé dans le bon diamètre ne présente pas de jeu. Il a l air assez qualitatif pour faire dans la durée. Le seul petit reproche que je peux lui faire et qu' il demande d être bien maintenu. Bon, je l ai fait à main levée et ça demande un peu de force... Si j avais un établi, j aurai simplement bloqué l outil avec un serez joint. Donc c est vraiment un petit reproche qui n en est pas vraiment pas un :)

Great little thing. Well-machined. Used it so far with wood drillbits but tested with a titanium coated HSS & didn’t seem to have a problem (might worry about heat buildup if drilling thick metal but take it slow). Pity it doesn’t go below 3mm but suspect that with bits less than 3mm being a bit more fragile they might risk catching & breaking. Obviously not as good as a drill press, but more convenient, better for tight spaces & cheaper even at what seems a bit of a steep price. Works well held on by hand (on wood at least) - just make sure that drill bit is straight in hole so it doesn’t catch - but would imagine better results could be had if clamped in place. Not had reason to use the feature but allows drilling into a square corner using groove on base which a drill press might struggle with without a jig.

Alternativlos für mich. Zum Vererben. Präzise und maßhaltig, grundsolide. Tonnenschwer. Nichts anderes käme mir ins Haus.

Love these drill guides - quality made. I bought most every one they make. Very pleased!!

Oggetto che ammetto un pelo costoso, ma di eccezionale fattura. Blocco di acciaio spesso, lavorato a laser per le tacche di precisione per poterlo posizionare e fori perfetti per forare dritto in tranquillità. Fa il suo lavoro alla grande essendo spesso non permette movimenti alla punta e fai i fori dritti. Più che soddisfatto. Arrivava da Amazon UK ed è arrivato veloce e puntuale come sempre.
