Part of the TH series, it accepts bars with a 0.25 inch inside diameter and fits into a 0.625 inch outside diameter bore. The overall length is 2.75 inches, and the head diameter measures 0.75 inches. This holder is installed by machinists and toolroom technicians working with small-diameter internal turning and grooving operations where precise bar retention is required.\u003c\/p\u003e\u003cp\u003eThe TH-106 is suited for small-bore internal turning, grooving, and undercutting applications on CNC and manual lathes. Its compact dimensions make it practical for tight-clearance setups on small workpieces. This holder does not include coolant-through capability, so it is best applied in dry cutting or flood-coolant environments where coolant-through delivery is not required. Typical applications include precision part production in job shops, toolrooms, and production machining environments.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e0.25 inch inside diameter accepts standard TH-series boring and grooving bars\u003c\/li\u003e\n\u003cli\u003e0.625 inch outside diameter for consistent, repeatable tool post or turret mounting\u003c\/li\u003e\n\u003cli\u003e0.75 inch head diameter provides a stable clamping surface\u003c\/li\u003e\n\u003cli\u003e2.75 inch overall length suits compact lathe setups\u003c\/li\u003e\n\u003cli\u003eNo coolant-through design simplifies setup in flood or dry cutting conditions\u003c\/li\u003e\n\u003cli\u003ePart of the MICRO 100 TH series for consistent fitment across the line\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned for use with MICRO 100 TH series boring and grooving bars with a 0.25 inch shank diameter.

Ensure the lathe or turning center is fully powered down and the spindle is locked before mounting or removing any tooling. Verify that the bar shank diameter matches the holder inside diameter before assembly, and secure all fasteners according to the machine tool manufacturer's specifications. Follow applicable shop safety procedures and machine tool operator guidelines during setup.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eInside Diameter\u003c\/strong\u003e: 0.25 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOutside Diameter\u003c\/strong\u003e: 0.625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHead Diameter\u003c\/strong\u003e: 0.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.75 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSeries\u003c\/strong\u003e: TH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCoolant Through\u003c\/strong\u003e: No\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.2 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: MICRO 100\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: TH-106\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"MICRO 100","offers":[{"title":"Default Title","offer_id":52043695489330,"sku":"TH-106","price":121.26,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/cc33b10effc23579972a0a20983a316c_3c1f1a0e-ec11-47ce-808c-7d6de125e0f9.jpg?v=1790029301","url":"https:\/\/voomisupply.com\/products\/micro-100-th-106-boring-grooving-bar-holder","provider":"Voomi Supply","version":"1.0","type":"link"}
