All the features of the Mafell A 18M bl Cordless Drill Driver, plus a hammer function with 38,950 blows per minute for concrete and masonry drilling applications!

Put away your extension cords:  the most precise portable drill press just became more portable!  Mafell’s ASB 18M bl is compatible with Mafell BST Drilling Stations thanks to its 1-11/16” (43mm) diameter clamping collar, and it packs more than enough power for the largest WoodOwl Ultra-Smooth Auger Bits.  With eleven different torque settings, 1st & 2nd gear options, and a variable-speed trigger – this drill/driver produces just the right amount of torque for a host of applications – and the accessory A-DMV 3x Torque Head is available for triple torque in extreme situations.  Smart buttons on top of the tool allows the user to quickly convert between hammer drilling, conventional drilling, screw-driving, and the innovative “impulse” function (to remove stripped screws, or drill on smooth surfaces such as tile).  All these features come in the ultra-durable and ergonomic design that one would expect from the best of the best Mafell tools.

The ASB 18M bl works perfectly with smaller lightweight batteries (total weight is 4.2 lbs without chuck) due to the highly-efficient 18 V brushless and processor-controlled technology.  Individual cell state and temperature are monitored for long service life, and battery charge level is viewable anytime with the press of a button.  The base of the drill has LEDs to highlight your work on the go, as well as two convenient magnetic bit holders and a handy belt clip that attaches to the left or right side of the machine.  For storage and transport, the compact 16” x 12” x 7” T-MAX carrying case holds all the ASB 18M bl components including two batteries and 120 V charger.  There's no need to store chuck keys or wrenches anymore – the chuck, bit holder, and accessory A-WV 18 Angle Head easily swap and tighten in seconds using the quick-release system!

There are two versions of the ASB 18M bl to choose from.  The “PURE” version is available for users who already have the compatible Mafell/Metabo Batteries and Charger, whereas the Complete ASB 18M bl comes with two Mafell 72 watt-hour batteries and the 120 V charger.
