I'm sure that I'm not alone in being confused by Makita's model numbers, so this is an attempt to help anyone interested in buying a Makita 18 volt combi drill or drill/driver. This only covers the Li-Ion range currently on the market and available (6 Nov 2016), not the now defunct NiCd and NiMH products. Earlier models which are no longer available such as the DHP451, DHP452, etc are also omitted. The categories are all mine but are an attempt to make sense of the type of work these tools should be expected to perform. As ever combi drills cannot be regarded as a replacement for even a basic SDS drill when drilling masonry (although te wo heavy duty models get pretty close) so if you want to use a lightweight combi to drill masonry in a trade environment don't be surprised when it dies prematurely. For drilling heavy metalwork such as structural steels on a regular basis or for regular hole sawing greater than 65mm I'd recommend a model with a metal gearbox AND a metal chuck - nothing else will withstand the stresses and strains of that sort of work

Combi drills (drills with a drilling, impact drilling and torque adjustable screwdriving setting) are all prefixed "DHP" in the UK

Drill/drivers (drills with a drilling and torque adjustable screwdriving setting) are all prefixed "DDF" in the UK. In general these are slightly lighter than the DHP variant (about 50gm). For some (not all) DHP model there is an equivalent DDF model, but they are less commonly sold and generally cost more.

Colours: Standard colour is Makita blue. Special edition models have been sold in white, red, black and metallic blue (only DHP456 and DHP481 AFAIK). The metallic colour is a sprayed finish and not hugely durable (white is a plastic colour)

In general and in common with other cordless tools most models feature plastic gearbox housings and chucks (exceptions are noted). AFAIK all Makita models use metal gears. All of Makita's drills now have 2-speed mechanical change gearboxes

Current production models appear to be: DHP458, DHP459, DHP481, DHP482, DHP483 and DHP484

Information has been checked against Makita official information. E&OE
