Eliminate Marking Process from Duct Channel Drilling! "TMD Puncher Gauge DPG-TMD" Newly Released

Niigata Seiki Co., Ltd. (Headquarters: Sanjo City, Niigata Prefecture, Representative Director: Toshiyuki Igarashi), a precision measuring instrument manufacturer, in collaboration with TomiDen Co., Ltd. (Headquarters: Takasaki City, Gunma Prefecture, Representative Director: Takahiro Tomizawa), has developed a new product for electrical contractors, the "TMD Puncher Gauge," which will be available from April 2026. This product is a dedicated gauge that allows quick and accurate positioning from the end face without marking when drilling holes in duct channels. Its unique structure, which is registered as a utility model (Registration No.: 3254976), significantly reduces on-site work time. ■ Main Applications - Positioning for drilling duct channels - Large-scale construction in factories, plants, commercial facilities, office buildings, etc. ■ Development Background In electrical construction sites, there are many situations where a large number of duct channels are installed in factories, commercial facilities, and buildings. Traditionally, drilling holes in these long members was a time-consuming and labor-intensive process involving alignment and marking. Upon receiving a development request from TomiDen Co., Ltd., Niigata Seiki began developing a dedicated gauge to solve this problem. TMD Puncher Gauge DPG-TMD: Direct drilling possible without marking ■ Product Features 【1】Drilling possible without marking (scribing) This product completely eliminates the conventional marking process. Since the position is determined simply by aligning it with the end face of the gauge, drilling can be performed quickly and repeatedly without measurement, proving highly effective in large-scale construction sites. 【2】Accurate positioning from 20mm to 50mm in 5mm increments The hole position can be easily set in 7 stages, from 20mm to 50mm in 5mm increments from the end face. Its unique multi-step structure supports positioning for drilling duct channels. 【3】Attaches to Negurosu Denko's "Channel Hole Puncher MAKD" It attaches to Negurosu Denko Co., Ltd.'s "Channel Hole Puncher MAKD." By using it in electrical construction sites where a large number of duct channels are installed, such as factories, plants, warehouses, logistics facilities, commercial facilities, large stores, and office buildings, construction time can be significantly reduced. 【4】Usable by anyone regardless of dominant hand The symmetrically arranged step shape allows insertion from both left and right directions. All workers can use it with the same procedure regardless of their dominant hand. Attaches to Negurosu Denko's "Channel Hole Puncher MAKD" with a symmetrical shape for insertion from both directions ■ Product Specifications Product Name: TMD Puncher Gauge Model Number: DPG-TMD Positioning Range: 20mm to 50mm (7 stages in 5mm increments) Compatible Model: Negurosu Denko Co., Ltd.'s Channel Hole Puncher MAKD Body Size: W56×H100×D34mm Body Weight: 150g Body Material: Stainless steel Country of Manufacture: Japan (Niigata Seiki's own factory) JAN Code: 4975846669031 Standard Retail Price: ¥5,720 (tax included) Release Date: April 2026 Sales Channels: Electrical material wholesalers, electrical construction material retailers, hardware stores, pro shops, home centers, e-commerce malls Target Users: Electrical contractors Product Page URL: https://www.niigataseiki.co.jp/newproducts/special_dpg-tmd/ ■ Intellectual Property Rights Type of IP: Utility Model Right Registration Status: Registered Registration Number: 3254976 Registration Date: February 26, 2026 Target Technology: Positioning gauge (overall configuration) that allows accurate and easy alignment when drilling long members *"Duct Channel®" is a registered trademark of Negurosu Denko Co., Ltd. 【About Niigata Seiki Co., Ltd.】 Niigata Seiki Co., Ltd. is a measuring tool manufacturer celebrating its 66th anniversary, with manufacturing, sales, and calibration of precision measuring tools as its main business.
