Eibenstock is a German power tool manufacturer founded in 1919. Its diamond core drill lineup spans compact dry-only models, versatile wet/dry combination units, and the PowerLine series built for continuous heavy-duty work.
This article covers Eibenstock's flagship models, the jobsite conditions each one suits best, the support structure, and bit availability.
The EHD 1500 is a 1,500W dry-only model handling diameters from 32 to 82 mm. It weighs just 3.9 kg, and an 82 mm bit designed specifically for electrical box cutouts is available for it. It is an easy-to-use model for interior renovation and electrical work where water use is not practical.
The ETN 162/3 is a 2,200W, 3-speed wet/dry combination unit. It handles wet concrete coring from 12 to 162 mm and dry brick coring from 12 to 202 mm. It is a model that can serve as the core machine for contractors whose base material changes from job to job.
The PLD 182.1 NT is part of the PowerLine range and is a model built for continuous heavy-duty operation. It handles wet coring up to 182 mm and dry coring up to 202 mm. Its aluminum housing and compact design allow it to work in confined spaces, making it the right choice for high-volume drilling and demanding applications.
Eibenstock is well suited for contractors who want to assign dedicated machines to specific tasks—from electrical and MEP cutouts to concrete coring and continuous drilling operations. The clear role separation between flagship models, the inclusion of a continuous-work-oriented series like the PowerLine, and the ease of tracing bit options, dealer contacts, and technical information through official channels all make Eibenstock a strong choice.
This site also features diamond core drills from a wide range of manufacturers beyond Eibenstock. Use this information to find the product that best fits your specific operational requirements.

Eibenstock was founded in 1919 and carries the Made in Germany designation. The company manufactures 80% of its components in-house and complies with the requirements of DIN EN ISO 9001:2015. Membership in EPTA and ZVEI can also be confirmed. It is a structure that makes the case for purchase straightforward for organizations that place a high priority on quality control and supply continuity.
With dry-only compact models, versatile wet/dry combination units, and the continuous-work-oriented PowerLine series all in the catalog, the lineup is especially well suited for companies whose requirements vary from site to site. Rather than forcing a single machine to handle MEP cutouts, electrical openings, and concrete coring simultaneously, the ability to select by specific jobsite condition is a defining strength of Eibenstock.
According to official information, Eibenstock operates its own in-house repair division and provides at least 10 years of continued repair support through its spare parts service. The website provides access to repair services, parts lists, extended warranty options, and a direct inquiry form, with dedicated technical support hours on weekdays clearly listed. Products are sold through specialist dealers, and a direct inquiry path is also available.
No project case studies were available on the official website at the time of research.
Genuine bits are available across both dry and wet types with broad coverage. From small-diameter MEP holes to large-diameter structural coring, the lineup is organized by connection standard—making it straightforward to plan the full system around the drill body. Extension shafts, water tanks, vacuum pumps, and dust extraction accessories are also available.

3 Diamond Core Drills, Matched to Your NeedPrioritize Lightweight
Japanese-Built Durability in a Serviceable Compact Design
Built to strict Japanese quality standards, this compact machine packs a high-performance motor into a 13.6 kg body. Robust against temperature swings and tough conditions—lightweight yet reliable enough to keep crews drilling with minimal downtime.
A proprietary control design that delivers both precision and light weight. The Automatic Feeding System reads drilling load in real time, physically preventing operator over-feeding and eliminating abnormal tool wear. Holds steady drilling speed and extends consumable life(*1)—even on sites with limited space or a high volume of small-diameter holes.
Prioritize Automation
Advanced Digital Control for Automation and On-Site Safety
Hilti Cut Assist digitally controls drilling pressure and water flow throughout the cut. Once set, the hole is drilled fully automatically. This drives labor savings and productivity gains on large-scale jobs with hundreds of holes.
Active Torque Control (ATC) instantly detects jamming of the core bit, and electronically stops sudden kickback that can cause workplace injuries. ATC meets strict safety standards for large-scale projects while reducing the risk of human error.
Prioritize Value
Professional Coring Performance at a Reasonable Price
Rig-based drills start in the $200s, while handheld models start in the $100s, offering affordable options across the lineup(*2). The drill delivers a strong ROI both as a backup for primary machine downtime and for rapid deployment at expanding jobsites.
A reliable mechanical gearbox and a rigid extruded-aluminum stand reflect a specialist manufacturer's focus on core drilling fundamentals. It reliably delivers precise drilling performance even at demanding jobsites, at a competitive cost.
