EDM hole drilling demand is climbing fast through 2026. Specifically, aerospace and medical device customers are pushing for smaller diameters, tighter tolerances, and faster cycle times than ever before. Furthermore, the rise of electric vehicles and advanced energy systems has opened entirely new applications for precision micro-hole work. As a result, the shops we serve here in Minnesota are reassessing what their hole drilling capability needs to be.
Industry analysts forecast the global drilling-type EDM market growing from $677.8 million in 2025 to roughly $885 million by 2030. In other words, the work is real, and it is coming. However, capturing it requires the right machine, the right setup, and the right partner. That is exactly what we provide at Iron Machine Tool.
The Boom Behind EDM Hole Drilling Demand
The 2026 surge reflects several converging trends. First, aerospace OEMs are ramping turbine blade production for both commercial and defense engines. Second, medical device makers continue to miniaturize implants, surgical tools, and drug delivery devices. Third, electric vehicle programs need cooling channels, fuel injector nozzles, and battery interconnects with hole geometries that conventional drilling cannot achieve.
These industries share one thing in common. Specifically, they cannot tolerate burrs, recast layers, or dimensional drift. Therefore, traditional drilling falls short. Small-hole EDM, however, makes holes without mechanical contact. As a result, hardened steels, titanium alloys, Inconel, and carbide all become workable materials at sub-millimeter diameters.
Why Minnesota Sits at the Center of the Surge
Minnesota holds a unique position in this expanding market. According to the Minnesota Department of Employment and Economic Development, the state has more than four times the national average labor concentration in medical device manufacturing. Furthermore, Minnesota is one of only two states in the country with medical devices as its top export. Medtronic, Boston Scientific, Abbott, and 3M all operate major facilities here.
For local precision shops, this concentration creates steady downstream demand. Specifically, every medical device company in the Twin Cities corridor needs suppliers who can drill micro-holes in titanium, stainless steel, and exotic alloys. Likewise, the aerospace and defense work clustered around Greater Minnesota adds to the demand pipeline. Therefore, hole drilling capability has become a competitive differentiator for Minnesota shops competing for high-value contracts.
Aerospace and Defense Drive Precision Limits
Aerospace customers represent roughly 40 percent of the small-hole EDM market. Specifically, turbine blade cooling holes drive much of that demand. Each blade can have hundreds of cooling holes, all positioned at compound angles, all needing tight diameter and depth control. Furthermore, fuel injector nozzles, multi-angle airfoil features, and lightweight structural components all rely on the smallest, hardest-to-reach hole work that only EDM can deliver.
Defense programs add another layer. Specifically, military aviation, naval propulsion, and advanced weapon systems all use precision micro-holes in hardened and exotic materials. As a result, aerospace and defense customers have driven significant investment in newer hole drilling machines across the country.
Medical Device Manufacturing Pushes Holes Smaller
The medical device segment is the fastest-growing slice of the small-hole EDM market. For example, biopsy needles, catheter tips, stents, pacemakers, and orthopedic implants all rely on micro-holes drilled with absolute precision. Furthermore, drug delivery devices and minimally invasive surgical tools require holes that cannot leave a recast layer or burr behind.
Here in Minnesota, this work hits especially close to home. Medtronic alone employs more than 90,000 people worldwide and counts our state as its operational headquarters. Likewise, Boston Scientific and 3M run substantial Minnesota operations. Therefore, when we hear from our customers about new contracts, medical device work is often what they are scaling up to deliver.
EV and Energy Bring New Applications
Electric vehicles and advanced energy systems represent the newest demand driver. Specifically, EV battery packs need precise drilling for cooling systems and electrical connections. Likewise, charging infrastructure depends on accurate machining of high-voltage components. Furthermore, hydrogen fuel cell development needs micro-machined plates and channels.
These applications often require materials and geometries that traditional drilling cannot handle. As a result, this technology has become a default capability for shops bidding on EV and energy work. Of course, the demand is still growing as more programs reach production scale through 2027 and beyond.
Four EDM Hole Drilling Machines We Offer at Iron Machine Tool
At Iron Machine Tool, we supply four machines, each built for a different point in the precision spectrum. Specifically, our lineup covers the H32Z manual, the SD-530 CNC, the SD-750 CNC, and the AD6L CNC submerged. Furthermore, each model serves a distinct shop profile and workload.
The H32Z is our manual hole drilling machine. It features a 23.6 by 11.8-inch worktable, X-Y travels of 13.8 by 9.8 inches, and a W-axis electrode stroke of 13.4 inches. In addition, it accepts electrode diameters from 0.008 to 0.124 inches, with an optional range up to 0.236 inches. As a result, the H32Z fits shops handling lower-volume precision work or those moving into hole drilling for the first time.
The SD-530 CNC adds automation and control. Specifically, it features XY travels of 21.6 by 11.8 inches, a 23.6-inch W-axis electrode travel, and a 14.2-inch Z-axis guide travel. Furthermore, it includes a 10-position automatic electrode changer and a 4-position guide changer as standard. In other words, the SD-530 supports longer unattended runs and faster setup changes.
The SD-750 CNC extends capacity for production environments. For example, it brings 27.5 by 17.7-inch XY travels and a 27.6-inch W-axis electrode travel. Likewise, it features a 15-position automatic electrode changer and the same 4-position guide changer. Therefore, the SD-750 suits shops handling larger workpieces or higher-volume runs.
The AD6L CNC submerged machine handles our most demanding work. Specifically, it features XY travels of 23.6 by 15.7 inches and a 19.7-inch W-axis electrode travel. In addition, optional 5th or 6th axis rotary or tilt-turn tables enable complex multi-axis hole geometries. Furthermore, it supports up to a 20-position electrode changer. As a result, the AD6L tackles the toughest aerospace and medical device geometries.
Choosing Between Manual, CNC, and Submerged Systems
Choosing the right machine starts with the work. For shops new to EDM hole drilling or running lower volumes, the H32Z manual and SD-530 CNC offer the cleanest entry path. A deeper look at both is available in Manual to First CNC: How the H32Z and SD-530 Help Minnesota Shops Get Into EDM Hole Drilling.
On the production side, the SD-750 and AD6L scale to higher-volume and more complex work. Notably, the AD6L submerged design opens up multi-axis geometries that other machines simply cannot reach. For details on these production-grade systems, see Inside the SD-750 and AD6L Submerged: Production EDM Hole Drilling for Minnesota’s Toughest Jobs.
Why EDM Hole Drilling Investments Make Sense Now
Timing for capital investment is favorable through 2027. First, the underlying demand from medical, aerospace, and EV applications is well-established. Second, federal manufacturing investment continues to support precision work. According to the National Institute of Standards and Technology, advanced manufacturing processes create novel materials and components with superior properties and performance — directly enabling the precision work this technology supports.
Furthermore, the productivity math has shifted. Specifically, modern CNC hole drilling machines let one operator run multiple cycles unattended. As a result, the labor cost per hole has dropped significantly compared with manual operations. In addition, automation reduces setup time between jobs, which matters in mixed-product shops handling many short runs.
