At 0.8mm head diameter, the #330 occupies the standard preparation size range for routine posterior restorative work, providing a cutting head that fits within the occlusal fissure access of most posterior teeth while delivering the pear-shaped geometry at the preparation walls and floor that the #330 bur designation specifies across all major carbide bur manufacturer catalogs.\u003cbr\u003e\u003cbr\u003eRestorative dentists who use pear-shaped burs for divergent wall amalgam preparations, occlusal reduction steps, and cavity refinement find Midwest Carbide Bur #330 the tungsten carbide pear-shaped FG bur for their active restorative operatory supply.\n?\nEach pack contains 100 individual FG #330 carbide burs in a clinic pack format providing a substantial operatory bur supply for active daily restorative use. Tungsten carbide construction provides three times the hardness of stainless steel at the cutting flute surfaces, maintaining the sharpness of the pear-shaped geometry across the preparation sequence and through multiple uses before replacement is indicated. Clinic pack quantity of 100 supports single-use or limited-use bur replacement protocols for high-volume restorative practices, providing sufficient supply to maintain consistent cutting performance across the full daily appointment schedule without mid-day restocking.\n?\nMidwest Carbide Bur #330 works through its pear-shaped head geometry where the bur head widens from the rounded tip to its maximum diameter at the shoulder, producing slightly divergent lateral wall cuts as the bur is advanced into the preparation to full depth, creating the characteristic pear cross-sectional preparation profile that the #330 designation produces in all compatible posterior tooth preparations.\u003cbr\u003e\u003cbr\u003eHigh concentricity achieved through meticulous manufacturing precision keeps the bur rotating on its intended axis without eccentric wobble during high-speed rotation, eliminating chatter and vibration that imprecise manufacture introduces at the cutting head during active preparation, and producing the smooth preparation walls and floors that restorative technique requires for accurate restoration adaptation and margin placement. Tungsten carbide cutting flutes at the bur head lateral surfaces and tip maintain their sharpness across the preparation sequence, cutting efficiently through enamel and dentin without the premature dulling that reduces cutting efficiency mid-preparation and requires increased pressure generating excess heat and patient discomfort at the tooth surface.\n?\nRestorative dentists placing Class I amalgam restorations where a divergent wall preparation design is indicated for mechanical retention find the #330 pear geometry produces the correct preparation profile in a single bur without requiring a shape change during the preparation sequence. Dental assistants setting up restorative trays for amalgam preparation appointments find the 100-count clinic pack covers the pear-shaped geometry needed alongside tapered fissure burs for standard posterior amalgam restorative procedures in a single per-geometry clinic pack order.\n?\nMidwest Carbide Bur, FG, Pear-Shaped, #330 gives dental practices a tungsten carbide, high-concentricity, chatter-free FG clinic pack bur in the 0.8mm #330 pear-shaped geometry for divergent wall cavity preparation, occlusal reduction, and cavity refinement in posterior amalgam and composite restorative procedures, in a 100-count pack suited for active daily use across posterior preparation workflows.\u003cbr\u003e\u003cbr\u003eFor dental offices ordering FG carbide bur supplies for restorative operatories, the Midwest #330 clinic pack delivers the pear geometry precision, tungsten carbide durability, and smooth preparation performance that consistent Class I restorative preparation requires.\u003c\/p\u003e","brand":"Midwest","offers":[{"title":"FG \/ Pear \/ 330","offer_id":51368744223041,"sku":"MI-FG330","price":174.25,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0932\/2525\/5233\/files\/31402_main.webp?v=1770267754","url":"https:\/\/carolinadental.com\/products\/midwest-fg-330","provider":"Carolina Dental Supply","version":"1.0","type":"link"}
