Bosch GSK18v Li Brad Nailer In Action - a Toolstop Guide

Bosch GSK 18 V-LIN 18V Cordless li-ion Brad Finishing NailerIn this quick guide we're going to show you how to affix skirting or other mouldings using a brad nailer. For a guide to choosing a the right brad or fixing nailer for you (and how to tell the difference) please refer to our buying guide here.

For this task we got some help from Bosch's Eric Streuli who used a Bosch GSK 18v Li brad nailer. We've got some spec on this power tool below.

Step 1
Release the safety lock
Step 2
Depress the nose against the skirting board
Step 3
Press the trigger

It really is that simple.

Of course, if you need to you can adjust the depth the brad nails are driven into the workpiece by turning the depth adjustment wheel on the side of the nailer.

Stats Worth Pointing Out

The Bosch GSK 18v Li is a bit of a beast. First off, no gas (ie combustion) and no pneumatics (ie air lines). This is purely driven by Bosch's 18v lithium-ion battery technology.

The triggering system is sequential and you're going to get around 3 nails fired per second, assuming you've mastered the above technique!

As it's a brad nailer, it handles brad nails of around 110 per magazine and of between 32 and 64mm in length with a diameter of 1.6mm, and it's compatible with Paslode and DeWalt 20 finish nails.

Up Close and Personal

Here are a few features you need to know about:
Bosch GSK 18 V-LIN 18V Cordless li-ion Brad Finishing Nailer

  1. Non-marring rubber nose guard: essential for when you're working on material that you simply can't mark!
  2. Tool-less Adjustable Depth-of-Drive: fast and easy adjustable nail depth control for more accuracy
  3. Lock-Out Switch: when engaged, disables tool when not in use

Ease of Use Features

Jammed nails are a reality when using a brad nailer (brad nails are thin and light and easily bent), so the presence of Bosch's "Tool-Free Jam Clearing" system on the GK 18v Li is a bonus. Simply lift the lid of the firing pin and remove the jammed nail.

Because brad nailers are used when you're finishing a job off, particularly in an area where appearance is important, it's good to know that the GK18v Li won't fire blanks. This protects the wood you're nailing.

Bosch claim that the GK 18v Li has the smallest diameter grip on class, along with large soft grip areas on the handle. If true then this means you'll probably be able to handle and use the GK18v Li for longer without experiencing user fatigue.

As mentioned the Bosch GK18v Li runs off Bosch's fabled 18v lithium-ion batteries.

Bosch claims you'll get around 700 32mm brad nails fired on one charge. This is a great choice of brad nailer if you've already bought into the Bosch 18v range of tools as you'll be able to quickly slap a battery into it and get nailing!

Typical Applications for the Bosch GK18v Li

We reckon this nailer is ideal for:

  •     Trim work: chair rail, staircase, base board etc
  •     Window and door casings and molding
  •     Soft wood 1x and 2x materials (i.e. pine)
  •     Hard wood 1x materials (i.e. oak, maple, birch, poplar)
  •     Composite trim materials

But be sure to check out our nailer buying guide to make sure you know the best nailer for you.

Finally, here's Eric from Bosch giving us a run through of the features of the GK18v Li and showing us it in action.

Hi Eric

Was looking at getting one of these guns because my Paslode can be a bit tempramental in the cold. Until that is I saw the price. Dearer than a Passy. And the weight. Half as heavy again as a Passy. And the size of it. Half as big again as a Passy. Must be tiring if your using above head height for any length of time. And as for the review from the lady who said it's just what she needs, doubt if she can pick it up. I'll stick to my Paslode and just keep the gas in my pocket.

I bought this a couple of weeks ago to replace some floorboards that had been damaged by woodworm.I was a little wary as I'm the clumsiest of people and thought it might be a little dangerous for me.This tool is a little diamond, I had the boards relayed within 2 hours, a hammer and nails would have taken me the whole day.It's surprisingly safe to use, not anywhere near as noisy as a hammer and really easy to master.I have a whole heap of jobs that this will save me time on.What a great little invention.

this would be ideal for my fiancé. We have just moved into our first home and it needs a complete overhaul. His current jobs are putting up architrave and sorting out the skirting which needs replacing in certain rooms. This tool would make his life much easier (and mine!)

Good bit of kit, although we have had probs with lithium batteries in the past

My husband would love one of these - boys and their toys!

This looks really easy to use. I have always been a bit scared of nail guns (think horror movies) but from the video it looks like I could use this one safely

I used one of these while helping a friend recently. Really easy to operate, even for a novice like me. Have LOADS to do in the old cottage we're renovating, so will no doubt get more experience...

Who wants no more nails when you can play with one of these bad boys " FIX ..... its got my nail in it"

This could be the product of my dreams, with a half finished house and a husband who is now suffering with arthritis, we were wondering how he was going to finish off all the DIY jobs hes started over the years (not a job for me ill add, I was banned from using wood in my woodwork class at school!) this would certainly make jobs like putting the new skirting round our bedroom, and putting together the sink vanity unit in the bathroom much easier for him. Plus I wouldnt have to be there to read all the instuctions as its quite simple to use and maintain :)

Looks like a great, effort saving tool, will definitely buy one

I've just watched the "How to nail skirting with a Bosch brad nailer" and I must say that as a 50+ lady, with occasional DIY experience it has removed my fear over the thought of using a nail gun product. I've only seen them on TV on occasional DIY programmes where they have frightened me. This actually reminded me of a stapler with the tension bar for the nails. Loved the easy way you could open and remove 'blockages', as this was another area I was worried about. I don't have a lot of physical strength and with neck problems any repeated movements are quite literally a pain- this would solve all those repeated hammering movements. Really impressed, thanks for a very useful, easy to follow tutorial.

My trademan could have done with one of these to speed the job along!

Is it really worth it?

looks excellent, I have had a gas Paslode for a few years now and get really fed up with the gas in the winter not firing. also very smelly in cupboards etc. Definately going to look into buying one of these.

Borrowed one of these off a colleague and was very impressed. Looking to upgrade to one of these in the near future

This sounds like an ideal nailer especially for someone like me who suffers from arthritis. Using a hammer & nail is impossible for me & this would be so much easier & very fast

Andrew Johnson on Sat, 01 Jun 2013 19:11:10 +0100 (Likes: 0 / Dislikes: 0

You can't beat an electric nailer. I've had one for years and in my opinion they are just as good as the gas one's. And as usual Bosch step up to the challenge and produce the goods that people want.

A nail gun is the greatest piece of kit! So useful in so many ways and for a range of jobs.....

i bought one of these 3 weeks ago now & i'm very impressed with it as i am with all bosch tools it takes abit of getting used to if your used to using a paslode which i was but all in all a excellent nail gun

This is a great item but have always been nervous about getting one as I know they can be quite dangerous in the wrong hands.guess I will have to bite the bullet and get one as got so much work to do in the house and garden that will take me until next century with standard hammer and nails.
