Bosch GBH 4-32 DFR Professional Rotary Hammer

Practical heavy duty rotary hammer, Bosch GBH 4-32 DFR – So, I am often amused by the fact that Bosch use the letters GBH as an entry for their rotary hammer descriptions. If ever grievous bodily harm, could be inflicted on bricks, some concrete and then the Bosch 4-32 is guilty. Light enough for the average bloke or person to manage with a good safety margin the capability of this machine is very wide indeed, and more importantly it comes as a kit, with a standard chuck included as well as the SDS + chuck, lubrication grease for the drill bits, and assortment of SDS plus bits of high-quality as well as a number of other extras. As of July 2022, pretty typical price is around $700 Australian. It is a 240 V tool, which to my mind still has an advantage in terms of being able to run literally all day without interruption and provides maximum power output consistently all the time. I have a Bosch 18 V rotary hammer as well, a small capacity one which is fantastic, but when really heavy hitting Is required the 432 is always ready. It fits my hand well, extremely well balanced, easy to use, very little vibration particularly when using Bosch 4 Cutterhead masonry bits, which are my favourite for drilling into masonry and concrete, it is not hard to go up the ladder with it takes no effort to drill a hole typically it’s using my hands is from 8 mm to 22 mm holes and in all these cases it is an effortless quick and comfortable tool to use. It is now a couple of years old and I am satisfied that its performance, reliability and capability genuinely warrant a five star rating and comments made in public reflecting my user experience.

I have a number of Bosch corded rotary hammers, I personally feel based on 20 years of use of them, that bunch really do make outstanding corded rotary hammers and as the inventors of the SDS system their Rotary hammer drills are just brilliant precision instruments which are complimented By the outstanding development if it’s the Bosch put into their SDS plus drill bits. I find of the combination outstanding and I also find and believe the value for money proposition with the 432 and its supporting gear is excellent, are you truly robust reliable capable machine which if anything the advertising for it sells it short, it is an outstanding machine that performs to the maximum not consistently all day. Anyone who buys this unit will The extremely satisfied with it

Top drill – For the money you would expect something, it certainly does the job. The main selling points for me were the safety features, an automatic shutoff when the drill bit jambs and trigger speed to allow a slow accurate start and total control. Bosch have a cheaper "blue" but it is in a lighter class, this heavy-weight monster is easier to use up a ladder than the light ones that you have to lean against.

Might not be a great "buy" but it's great to use.... :)
