Here is a previous response from Dremel. I got this reply from Dremel on the subject of a hot Flex-Shaft attachment. There will be some amount of heat present but nothing unbearable to the touch. Excessive heat is a product of either over or under-lubrication, using the wrong type of lubrication, or operating the flex shaft with a sharp bend. Any one of these will cause parts of the cable to overheat. The handpiece should be comfortable to hold in use and the flex shaft or spring around the flex shaft should not overheat. The only piece that requires lubrication is the inner core of the flex shaft.\u003c\/p\u003e\u003cp\u003eTo lubricate, unscrew the flex-shaft assembly from the motor housing. Pull the center core out of the flex-shaft shaft (it should come out very easily) and wipe it down with a dry rag. Wipe a very thin film of good quality, high-temperature grease on the center core. We recommend our shaft lubricant #90952 or any type of good quality grease that does not break down under heat, such as automotive wheel bearing grease. The inner core requires lubrication after every 25-30 hours of use. Again, only a very thin (barely visible) coat of grease. Too much grease or using the wrong type of lubrication will cause the unit to overheat. Also, when too much lubrication is applied to the inner core it will run down to the handpiece causing overheating. This in effect will prematurely ruin the bearings. A small amount of grease is all that is needed.\u003c\/p\u003e","brand":"Bosch - NZ","offers":[{"title":"Default Title","offer_id":45131090362421,"sku":"B-2610914543","price":21.9,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0660\/8621\/files\/Dremel-Flex-Shaft-225-Inner-Core-2610914543-A.jpg?v=1776675840","url":"https:\/\/testntools.co.nz\/products\/dremel-flex-shaft-225-inner-core-2610914543","provider":"Testntools","version":"1.0","type":"link"}
