SDS-MAX tip
SDS-MAX drill bits
Effective penetration defines the SDS-MAX bit , an essential element for making large diameter holes in concrete and masonry. The helical geometry with variable pitch facilitates the rapid evacuation of debris, preventing overheating and blockage during deep drilling. These Makita accessories are designed with plasma-welded tungsten carbide inserts that ensure exceptional resistance even in the most abrasive materials.
The head design, with carefully studied angles, optimizes feed rate and reduces the required effort. The asymmetrical arrangement of the inserts generates an automatic centering effect that improves hole accuracy and reduces vibrations transmitted to the operator. The lateral flutes feature strategic reinforcements at the points of greatest stress, increasing overall structural strength .
The reinforced spiral effectively transfers rotation from the hammer to the cutting head, maintaining integrity even under high torsional loads. The differentiated heat treatment provides greater elasticity in the tip body to absorb shock, while the contact areas with the material achieve superior hardness to resist constant abrasion.
The SDS-MAX coupling ensures a secure fit and direct transmission of impact energy, increasing energy efficiency and reducing processing times. The transition zone between the shank and the spiral has a larger diameter, reinforcing the critical point subject to greater stress during use.
The tungsten carbide inserts are welded with micrometric precision and feature different geometries based on the tip diameter: the smaller models use inserts with more acute angles for easier penetration, while the large-diameter versions use more robust cutting edges to withstand greater lateral stresses.
The size range includes diameters from 12 to 52 mm with working lengths up to 1200 mm for special applications. The latest models incorporate anti-vibration technologies that significantly reduce operator fatigue during prolonged work sessions, improving accuracy and productivity in serial drilling.
