Sandvik GC4340 vs Tungaloy AH725 Steel Milling Grades Compared: CVD vs PVD Coatings, Edge Toughness and Cutting Parameters Explained
Milling steel is a thermal event with a rhythm section: every insert in a face mill or square-shoulder cutter leaves the cut hundreds of times per minute, and each exit is a small shock. Indexable milling grades therefore have to survive a combination of temperature, interrupted engagement and edge loading that turning grades never see. …
Parting Off and Grooving Tool Selection Guide: Insert Width, Chip Former Geometry, Grades and Cutting Parameters Compared
Why Parting Off Is the Most Demanding Turning Operation Parting off — cut-off turning — looks simple on a process sheet: one radial plunge, one finished part. In practice it is the operation that breaks the most inserts, produces the most chatter, and generates the highest scrap rate on any lathe. The reason is geometric. …
Iscar IC908 vs Vargus VM7 Thread Turning Inserts Compared: Grades, Full vs Partial Profile Geometry and Cutting Parameters Explained
Thread Turning Insert Grades and Geometry: The Two Variables That Decide Thread Quality Thread turning looks deceptively simple. The machine feeds the tool at exactly the thread pitch, the insert plunges a triangular form into a rotating bar, and a thread appears. In practice, most threading problems on a lathe — torn crests, chipped tips, …
Aerospace Aluminum High-Speed Milling Tool Selection Guide: Polished Carbide, PCD End Mills and Cutting Parameters for 6061/7075 Explained
Aluminum alloys are the backbone of aerospace structural components, and 6061-T6 and 7075-T6 remain the two most machined grades in the industry. While aluminum is often described as an easy-to-cut material, achieving high material removal rates (MRR), flawless surface finish, and long tool life in production requires a disciplined tool-selection strategy. This guide walks through …
Face Milling Steel Compared: Sandvik GC4240 vs Kyocera PR1225 Insert Grades, Geometry and Cutting Parameters
Face milling is the most common milling operation in machine shops working with ISO P steels, and it is also where insert grade selection has the most direct impact on productivity and tool life. Two of the most widely specified grades in this segment are Sandvik GC4240 and Kyocera PR1225. Both are CVD-coated carbide grades …
Inconel 718 Turning Insert Selection Guide: Sandvik vs Iscar Grades, Chipbreaker Geometry and Cutting Parameters Compared
Inconel 718 is the workhorse nickel-based superalloy of the aerospace, gas turbine and energy industries, and it is also one of the most punishing materials a cutting tool can face. Heat, work hardening and an abrasive microstructure combine to destroy ordinary carbide grades within minutes. Choosing the right turning insert — the correct substrate, coating …
Walter Tiger·tec Silver Turning Grades Explained: CVD Coating Architecture, Grade Selection, and Cutting Parameters for Steel and Stainless Steel
Among CVD-coated carbide families for turning, few have achieved the catalogue longevity and shop-floor familiarity of Walter’s Tiger·tec Silver generation. Introduced as the successor to the original Tiger·tec grades, the Silver programme reorganised Walter’s turning assortment around a smaller set of universal grades, each covering a wide slice of the ISO application map. The result …
Aluminum High-Speed Milling End Mill Selection Guide: YG-1 vs OSG Geometry, Coatings, and Cutting Parameters for 6061-T6 and 7075-T6
Why Aluminum Milling Deserves Its Own Tooling Strategy Aluminum alloys such as 6061-T6 and 7075-T6 can be milled at spindle speeds three to five times higher than steel, yet many shops still ruin parts — and end mills — by applying steel-machining logic to non-ferrous work. The failure modes are distinctive: built-up edge (BUE), chip …
Mitsubishi vs Tungaloy Steel Turning Inserts Compared: Grade Technology, Chipbreaker Design, and Cutting Parameters for ISO P Steels
Why Steel Turning Deserves a Brand Comparison Carbon and alloy steels are still the highest-volume workpiece family in general machining, which makes ISO P turning the most competitive segment of the carbide insert market. Two Japanese manufacturers approach this segment from visibly different directions. Mitsubishi Materials has built its steel-turning reputation on finely tuned PVD-coated …
Iscar SUMOCHAM Exchangeable-Head Drill System Explained: Head Selection, IC908 Grade Technology, and Cutting Parameters for Steel, Stainless Steel and Superalloys
In high-volume machining, the true cost of a hole is rarely the price of the tool itself. It is machine downtime during tool changes, inconsistent hole quality across shifts, and the logistics of sending solid carbide drills out for regrinding. Iscar built the SUMOCHAM family to attack exactly these costs: an exchangeable-head drilling system in …
