Therefore I shall not go into all the points of the device, but only on particularly annoying details: The chuck is beneath contempt, even the cheaper BHP453 has a Röhm lining, here it is a Jacobs - or possibly its cheap replica. The corresponding thereto problems gather you Heikos rating. For the price this is a nogo. Complementing Heikos review I can say that I was also clearly confirmed by Makita Germany that the BHP 454 "Made in China" is and that has me on my direct request, whether I should change brands, advised the BHP451 to grab, the well should indeed be a discontinued model, but still is a real Makita. On the market it is also hardly more expensive than the 454. So I have done it and am now happy again. In - hopefully also - future when the BHP451 should then be floored, I'll probably have to say goodbye to "my" brand. Metabo has become even handier. The professionals had conceded that there certainly are other brands, Festool example, but the cost in the market and a whole corner more.
Conclusion: Finger of a device whose price is situates in the professional class away, but its quality is reminiscent of DIY waste. Either you buy Baumarkt-quality construction market prices or professional goods for real money, which is not worth the money BHP454.
