Hitachi 2-cutter SDS Plus drills with double helix – faster drilling and professional performance

General Description

The 2-cutter double helix SDS Plus drills meet the highest quality standards and are designed for the professional end-user. Hitachi brings a recent innovation with a newly developed drill that sets a new benchmark in performance.

Tested in extreme conditions, these drills have proven their quality through high efficiency and performance. The 2-cutter concept is based on a central carbide tip, which offers multiple advantages during drilling.

The cross-section centering tip ensures fast and concentric drilling. Additionally, the three "power breakers" transfer impact energy to four contact points, simultaneously creating micro-fissures and significantly increasing drilling speed.

The special helix optimizes dust and debris evacuation, reduces friction and vibrations, while the more robust back end improves energy transfer and lowers the risk of breakage. Even in reinforced concrete, the dynamic chisel-shaped head quickly passes through the material and helps efficiently evacuate drilling debris.

Key Benefits

Faster and concentric drilling due to the cross-section centering tip.
More efficient impact transfer on four contact points for greater working force.
Improved dust and debris evacuation, reducing the risk of hole clogging.
Reduced friction with the hole walls, contributing to better drilling speed.
Lower risk of breakage due to the more robust and rigid construction of the back end.
Reduced vibrations, less strenuous drilling for the operator and rotary hammer.
Performance in reinforced concrete and greater resistance to impact with rebar.
Drilling speed +12% compared to the old Hitachi SDS Plus range.

Reinforced concrete	Dynamic chisel-shaped head; side edges of the carbide insert enlarged by ~35% vs. previous model
Blocking probability	Reduced, including lateral contact with rebar
Drilling speed increase	Over 12% compared to the old Hitachi SDS Plus range

The vario flute design at the front offers greater dust and debris transport capacity, contributing to clean and constant drilling without speed drops caused by clogging. At the same time, the narrow conical shape reduces friction with the hole walls and supports faster penetration.

For working in reinforced concrete, the side edges of the carbide insert have been enlarged by approximately 35% compared to the previous model, which increases resistance to impact with rebar and reduces the risk of blocking.

How to use the product

Mount the drill bit in the compatible SDS Plus chuck of the rotary hammer.
Position the centering tip on the working point and begin drilling, keeping the drill aligned for a concentric hole.
As you drill, the fluted helix optimizes dust and debris evacuation, maintaining working speed.
