These have 8mm precision ground tool steel shanks and CNC milled, heat treated tool steel heads. Each is hand lapped and checked for accuracy on a surface plate with gage blocks. Much more durable and accurate than the original part. Deckel wants about $100 ea. for these consumable parts. Here is a superior part for a bit less money.Thank you for your support! 100% of the proceeds go to my retired toolmaker friend.
